HD74HC4518, HD74HC4520 Dual BCD Up Counters Dual Binary Up Counters REJ03D0653–0200 (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.
