| www..com MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1-of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The MC54/74HC138A is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC138A decodes a three-bit Address to one-of-eight active-low outputs. This device features three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chip-selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states. * 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: 100 FETs or 29 Equivalent Gates LOGIC DIAGRAM 1 2 3 15 MC54/74HC138A 16 1 J SUFFIX CERAMIC PACKAGE CASE 620-10 16 1 N SUFFIX PLASTIC PACKAGE CASE 648-08 16 1 D SUFFIX SOIC PACKAGE CASE 751B-05 16 1 DT SUFFIX TSSOP PACKAGE CASE 948F-01 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXAD MC74HCXXXADT ACTIVE-LOW OUTPUTS Ceramic Plastic SOIC TSSOP A0 ADDRESS INPUTS A1 A2 Y0 14 Y1 13 Y2 12 Y3 11 Y4 10 Y5 9 Y6 7 Y7 PIN ASSIGNMENT A0 A1 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC Y0 Y1 Y2 Y3 Y4 Y5 Y6 CHIP- SELECT INPUTS CS1 CS2 CS3 6 4 5 PIN 16 = VCC PIN 8 = GND A2 CS2 CS3 CS1 Y7 FUNCTION TABLE Inputs X X L H H H H H H H H X H X L L L L L L L L H X X L L L L L L L L X X X L L L L H H H H X X X L L H H L L H H X X X L H L H L H L H H H H L H H H H H H H H H H H L H H H H H H H H H H H L H H H H H Outputs H H H H H H L H H H H H H H H H H H L H H H H H H H H H H H L H H H H H H H H H H H L H H H H H H H H H H H L CS1CS2 CS3 A2 A1 A0 Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 GND H = high level (steady state); L = low level (steady state); X = don't care 10/95 (c) Motorola, Inc. 1995 1 REV 6 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 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 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 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 II 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 II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIIIIIIIIIIIII II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII I I III I I I IIIIIIIIIIIIIIIIIIIIIII I IIIIIIIIIIIIIIIIIIIIIII III I III I I I I IIIIIIIIIIIIIIIIIIIIIII I I IIIIIIIIIIIIIIIIIIIIIII III I III I I III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII IIIIIIIIIIIIIIIIIIIII II I IIIIIIIIIIIIIIIIIIIIIII III I IIIIIIIIIIIIIIIIIIIIIII III 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.

For any other combination of CS1, CS2, and CS3, the outputs are at a logic high. OUTPUTS Y0 - Y7 (Pins 15, 14, 13, 12, 11, 10, 9, 7) Active-low Decoded outputs. These outputs assume a low level when addressed and the chip is selected. These outputs remain high when not addressed or the chip is not selected.
