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 µA

• 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
