74ALS163B - 4-bit binary counter

General Description

Synchronous presettable 4-bit binary counters (74ALS161B, 74ALS163B) feature an internal carry look-ahead and can be used for high speed counting.

Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock.

The clock input is buffered.

Key Features

  • 74ALS161B/74ALS163B 4-bit binary counter, asynchronous reset 4-bit binary counter, synchronous reset.
