HD74HC4518/HD74HC4520

Dual BCD Use Converters/Dual Binary Up Converters

Description

The HD74HC4518 dual BCD counter and the HD74HC4520 dual binary counter consist of two identical,

independent, internally synchronous 4-stage counters. The counter stages are type D flip-flops, with

interchangeable Clock and Enable lines for incrementing on either the positive-going or negative-going

transition as required when cascading multiple stages. Each counter can be cleared by applying a high

level on the Reset line. In addition, the HD74HC4518 will count out of all undefined states within two

clock periods. These complementary MOS up counters find primary use in multi-stage synchronous or

ripple counting applications requiring low power dissipation and/or high noise immunity.
