Features • ’HC161, ’HCT161 4-Bit Binary Counter, Asynchronous Reset • ’HC163, ’HCT163 4-Bit Binary Counter, Synchronous Reset • Synchronous Counting and Loading • Two Count Enable Inputs for n-Bit Cascading • Look-Ahead Carry for High-Speed Counting • Fanout (Over Temperature Range) - Sta

Presettable synchronous 4-bit binary counter; asynchronous reset

1. General description The 74HC161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positivegoing edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset HI

Presettable synchronous 4-bit binary counter; asynchronous reset

GENERAL DESCRIPTION The 74HC/HCT161 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. FEATURES • Synchronous counting and loading • Two count enable inputs for n-bit cascading • Positive
