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.
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).
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
