MC74HC161A/D
High–Performance Silicon–Gate CMOS
The MC74HC161A and HC163A are identical in pinout to the
LS161 and LS163. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with
LSTTL outputs.
The HC161A and HC163A are programmable 4–bit binary counters
with asynchronous and synchronous reset, respectively.
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
