| MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1-of-10 Decoder High-Performance Silicon-Gate CMOS The MC74HC42 is identical in pinout to the LS42. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC42 decodes a BCD Address to one-of-ten active low outputs. For Address inputs with a hexadecimal equivalent greater than 9, all outputs, Y0 - Y9, remain high (inactive). * * * * * * Output Drive Capability: 10 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: 104 FETs or 26 Equivalent Gates 16 1 MC74HC42 N SUFFIX PLASTIC PACKAGE CASE 648-08 16 1 D SUFFIX SOIC PACKAGE CASE 751B-05 ORDERING INFORMATION MC74HCXXN MC74HCXXD Plastic SOIC PIN ASSIGNMENT LOGIC DIAGRAM Y0 Y1 1 A0 (LSB) 15 2 3 A1 BCD ADDRESS INPUTS A2 13 14 4 5 6 7 9 10 A3 (MSB) 12 11 Y2 Y0 Y1 Y2 Y3 GND Y4 Y5 Y6 Y7 Y8 Y9 ACTIVE LOW OUTPUTS 8 9 Y7 Y3 Y4 Y5 Y6 1 2 3 4 5 6 7 16 15 14 13 12 11 10 VCC A0 A1 A2 A3 Y9 Y8 PIN 16 = VCC PIN 8 = GND 10/95 (c) Motorola, Inc. 1995 1 REV 6 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 III I I I I 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 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 II I I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII 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 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.
