| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS The MC54/74HC157A is identical in pinout to the LS157. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in noninverted form. A high level on the Output Enable input sets all four Y outputs to a low level. The HC157A is similar in function to the HC257 which has 3-state outputs. * * * * * * Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A * Chip Complexity: 82 FETs or 20.5 Equivalent Gates MC54/74HC157A J SUFFIX CERAMIC PACKAGE CASE 620-10 1 16 16 1 N SUFFIX PLASTIC PACKAGE CASE 648-08 D SUFFIX SOIC PACKAGE CASE 751B-05 DT SUFFIX TSSOP PACKAGE CASE 948F-01 16 1 16 1 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXAD MC74HCXXXADT Ceramic Plastic SOIC TSSOP LOGIC DIAGRAM 2 5 11 14 4 3 6 10 13 7 9 12 Y0 Y1 Y2 Y3 DATA OUTPUTS A0 NIBBLE A INPUTS A1 A2 A3 B0 NIBBLE B INPUTS B1 B2 B3 PIN ASSIGNMENT SELECT A0 B0 Y0 A1 B1 Y1 GND 1 15 PIN 16 = VCC PIN 8 = GND 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC OUTPUT ENABLE A3 B3 Y3 A2 B2 Y2 SELECT OUTPUT ENABLE FUNCTION TABLE Inputs Output Enable H L L Select X L H Outputs Y0 - Y3 L A0 - A3 B0 - B3 X = don't care A0 - A3, B0 - B3 = the levels of the respective Data-Word Inputs. 2/97 (c) Motorola, Inc. 1997 1 REV 7 MC54/74HC157A II I II I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I IIIIIIIII IIIIIIIIIIIIIIIIIIIIIII I I II I I I II I I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I III I I I I I I II I II I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIII IIIIIIIIIIIIIIIIIIIIIII I II I I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I III I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I I II IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I III I I I I I I II I I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I II I II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIII III I IIII II I I IIIIIIIIIIIIIIIIIIIIIII III I I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIII III III II I I I IIIIIIIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III III I I II IIIIIIIIIIIIIIIIIIIIIII III I I IIIIIIIIIIIIIIIIIIIIIII III II I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIII I I II I I I I I I I IIIIIIIIIIIIIIIIIIIIIII II IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIII I I III I I I I I II IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I III I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII IIIIII I I IIIIIIIIIIIIIIIIIIIIIII I I I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII MAXIMUM RATINGS* Symbol VCC Vin Parameter Value Unit V V V DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) - 0.5 to + 7.0 - 0.5 to VCC + 0.5 - 0.5 to VCC + 0.5 20 25 50 750 500 450 Vout Iin DC Output Voltage (Referenced to GND) DC Input Current, per Pin mA mA mA Iout DC Output Current, per Pin ICC PD DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic or Ceramic DIP SOIC Package TSSOP Package Storage Temperature mW Tstg TL - 65 to + 150 260 300 This device contains protection circuitry to guard against damage due to high static voltages or electric fields. 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. v v _C _C Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP, SOIC or TSSOP Package) (Ceramic DIP) * Maximum Ratings are those values beyond which damage to the device may occur.

The data present on these pins is transferred to the outputs when the Select input is at a low level and the Output Enable input is at a low level. The data is presented to the outputs in noninverted form. B0, B1, B2, B3 (Pins 3, 6, 10, 13) Nibble B inputs. The data present on these pins is transferred to the outputs when the Select input is at a high level and the Output Enable input is at a low level. The data is presented to the outputs in noninverted form. OUTPUTS Y0, Y1, Y2, Y3 (Pins 4, 7, 9, 12) Data outputs. The selected input Nibble is presented at these outputs when the Output Enable input is at a low level. The data present on these pins is in its noninverted form. For the Output Enable input at a high level, the outputs are at a low level. CONTROL INPUTS Select (Pin 1) Nibble select. This input determines the data word to be transferred to the outputs. A low level on this input selects the A inputs and a high level selects the B inputs. Output Enable (Pin 15) Output Enable input. A low level on this input allows the selected input data to be presented at the outputs. A high level on this input sets all outputs to a low level.
