MC74F163A - (MC74F161A / MC74F163A) SYNCHRONOUS PRESETTABLE BINARY COUNTER

Download the MC74F163A datasheet PDF. This datasheet also covers the MC74F161A variant, as both devices belong to the same (mc74f161a / mc74f163a) synchronous presettable binary counter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MC74F161A and MC74F163A count in modulo-16 binary sequence.

From state 15 (HHHH) they increment to state 0 (LLLL).

The clock inputs of all flip-flops are driven in parallel through a clock buffer.

SYNCHRONOUS PRESETTABLE BINARY COUNTER The MC74F161A and MC74F163A are high-speed synchronous modulo-16 binary counters. They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters. The MC74F161A has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW. The MC74F163A has a Synchronous Reset input that overrides counting and parallel loading and allows the outputs to be simultaneously reset on the rising edge of the clock.
