MC74HC161A: Presettable Counter

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.

Features
  • 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 mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 192 FETs or 48 Equivalent Gates
  • Pb-Free Packages are Available*
Applications
  • Industrial
