MC74HC147DS 数据手册

SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

The MC74HC147 is identical in pinout to the LS147. The device inputs are

compatible with standard CMOS outputs; with pullup resistors, they are

compatible with LSTTL outputs.

N SUFFIX

PLASTIC PACKAGE

CASE 648–08

This device encodes nine active–low data inputs to four active–low BCD

Address Outputs, ensuring that only the highest order active data line is

encoded. The implied decimal zero condition is encoded when all nine data

inputs are at a high level (inactive).

D SUFFIX

SOIC PACKAGE

CASE 751B–05

•

Output Drive Capability: 10 LSTTL Loads

Outputs Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 2 to 6 V

ORDERING INFORMATION

Low Input Current: 1 µA
