MC54/74HC160
MC54/74HC162
The MC54/74HC160 and HC162 are identical in pinout to the LS160 and
LS162, respectively. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC160 and HC162 are programmable BCD counters with asynchro-
nous and synchronous Reset inputs, respectively.
• 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: 234 FETs or 58.5 Equivalent Gates
