7490 - Decade and Binary Counter

Download the 7490 datasheet PDF. This datasheet also covers the DM7 variant, as both devices belong to the same decade and binary counter family and are provided as variant models within a single manufacturer datasheet.

General Description

The DM7490A monolithic counter 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.

DM7490A Decade and Binary Counters August 1986 Revised March 2000 DM7490A Decade and Binary Counters General Description The DM7490A monolithic counter 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. The counter has a gated zero reset and also has gated setto-nine inputs for use in BCD nine’s complement applications. To use the maximum count length (decade or four-bit binary), the B input is connected to the QA output. The input count pulses are applied to input A and the outputs are as described in the appropriate Function Table.
