74LS161 - BCD DECADE COUNTERS/4-BIT BINARY COUNTERS

Datasheet Summary

Description

The LS160A / 161A / 162A / 163A are 4-bit synchronous counters with a synchronous Parallel Enable (Load) feature.

The counters consist of four edge-triggered D flip-flops with the appropriate data routing networks feeding the D inputs.

Features

  • 54/74LS163A AC SETUP.

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS The LS160A / 161A / 162A / 163A are high-speed 4-bit synchronous counters. They are edge-triggered, synchronously presettable, and cascadable MSI building blocks for counting, memory addressing, frequency division and other applications. The LS160A and LS162A count modulo 10 (BCD). The LS161A and LS163A count modulo 16 (binary.) The LS160A and LS161A have an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock and all other control inputs. The LS162A and LS163A have a Synchronous Reset (Clear) input that overrides all other control inputs, but is active only during the rising clock edge.
