Overview
MC74HC161A, MC74HC163A Presettable Counters 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.
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 • These are Pb−Free Devices http://onsemi.
