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
