DM74LS93N - Decade and Binary Counters

Download the DM74LS93N datasheet PDF. This datasheet also covers the DM74LS93 variant, as both devices belong to the same decade and binary counters family and are provided as variant models within a single manufacturer datasheet.

General Description

Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the ’LS90 and divideby-eight for the ’LS93 All of these counters have a gated zero re
