| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 3-State D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS The MC74HC173 is identical in pinout to the LS173. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. Data, when enabled, are clocked into the four D flip-flops with the rising edge of the common Clock. When either or both of the Output Enable Controls is high, the outputs are in a high-impedance state. This feature allows the HC173 to be used in bus-oriented systems. The Reset feature is asynchronous and active high. * * * * * * Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity 208 FETs or 52 Equivalent Gates LOGIC DIAGRAM D0 14 D1 13 D2 12 D3 11 3 Q0 4 Q1 5 Q2 6 Q3 16 MC74HC173 N SUFFIX PLASTIC PACKAGE CASE 648-08 1 16 1 D SUFFIX SOIC PACKAGE CASE 751B-05 ORDERING INFORMATION MC74HCXXXN MC74HCXXXD Plastic SOIC PIN ASSIGNMENT OE1 OE2 Q0 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC RESET D0 D1 D2 D3 DE2 DE1 DATA INPUTS 3-STATE NONINVERTING OUTPUTS Q1 Q2 Q3 CLOCK CLOCK 7 DE1 9 DE2 10 RESET 15 OUTPUT ENABLES OE1 1 2 OE2 VCC = PIN 16 GND = PIN 8 GND DATA- ENABLES FUNCTION TABLE Inputs Output Enables OE1 L L L L L L L L L H H OE2 L L L L L L L L H L H Reset H L L L L L L L X X X Clock X L H Data Enables DE1 X X X H X L L X X X X DE2 X X X X H L L X X X X Data D X X X X X L H X X X X Output Q L No Change No Change No Change No Change L H No Change High Impedance High Impedance High Impedance X X X 10/95 (c) Motorola, Inc. 1995 1 REV 6 IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III I I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIII I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIII IIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I III IIIIII I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I IIIIIIIIIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII III I III I I I I IIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIII III I III I I II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII III III I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII III III I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII III III I I * Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.

Data on these pins, when enabled by the Data-Enable Controls, are entered into the flip-flops on the rising edge of the clock. CLOCK (Pin 7) Clock input. OUTPUTS Q0, Q1, Q2, Q3 (Pins 3, 4, 5, 6) 3-state register outputs. During normal operation of the device, the outputs of the D flip-flops appear at these pins. During 3-state operation, these outputs assume a high- impedance state. CONTROL INPUT Reset (Pin 15) Asynchronous reset input. A high level on this pin resets all flip-flops and forces the Q outputs low, if they are not already in high-impedance state. DE1, DE2 (Pins 9, 10) Active-low Data Enable Control inputs. When both Data Enable Controls are low, data at the D inputs are loaded into the flip-flops with the rising edge of the Clock input. When either or both of these controls are high, there is no change in the state of the flip-flops, regardless of any changes at the D or Clock inputs. OE1, OE2 (Pins 1, 2) Output Enable Control inputs. When either or both of the Output Enable Controls are high, the Q outputs of the device are in the high-impedance state. When both controls are low, the device outputs display the data in the flip-flops.
