MC74HC161AN Description

Short technical summary and product information.

The MC74HC161AN is a high-performance silicon-gate CMOS presettable counter manufactured by ON Semiconductor. This device is identical in pinout to the LS161 and LS163, with inputs compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used.

 

Key features include an operating voltage range of 2.0 to 6.0 V, low input current of 1.0 µA, and an output drive capability of 10 LSTTL loads. The MC74HC161A is a binary counter with asynchronous reset, while the MC74HC163A features synchronous reset. The device exhibits high noise immunity characteristic of CMOS devices and is in compliance with JEDEC Standard No. 7A.

 

Available in multiple package types including SOIC-16, TSSOP-16, PDIP-16, and SOEIAJ-16, the MC74HC161AN is suitable for various digital logic applications requiring reliable counting and resetting functions.
