Dual BCD Up Counters
Dual Binary Up Counters

(Previous ADE-205-542)
Rev.2.00
Mar 30, 2006
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.
