DM74ALS162B - Synchronous Four-Bit Counter

Download the DM74ALS162B datasheet PDF. This datasheet also covers the DM74ALS161B variant, as both devices belong to the same synchronous four-bit counter family and are provided as variant models within a single manufacturer datasheet.

Description

These synchronous presettable counters feature an internal carry look ahead for application in high speed counting designs.

The DM74ALS162B is a four-bit decade counter, while the DM74ALS161B and DM74ALS163B are four-bit binary counters.

DM74ALS161B • DM74ALS162B • DM74ALS163B Synchronous Four-Bit Counter April 1984 Revised February 2000 DM74ALS161B • DM74ALS162B • DM74ALS163B Synchronous Four-Bit Counter General Description These synchronous presettable counters feature an internal carry look ahead for application in high speed counting designs. The DM74ALS162B is a four-bit decade counter, while the DM74ALS161B and DM74ALS163B are four-bit binary counters. The DM74ALS161B clears asynchronously, while the DM74ALS162B and DM74ALS163B clear synchronously. The carry output is decoded to prevent spikes during normal counting mode of operation.
