7493 Datasheet PDF – Decade and Binary Counter – TI

This is a kind of TTL.

Part Number : 7493

Function : Decade and Binary Counter

Package : DIP, SOP 14 Pin Type

Manufacturers : National ( Texas Instruments )

Pinouts :

7493 pinouts

 

Description :

Each of these monolithic counters contains four master slave flip-flops and additional gating to provide a divide-by two counter and a three-stage binary counter for which the count cycle length is divide-by-five for the 90A and divide by-eight for the 93A.
All of these counters have a gated zero reset and the 90A also has gated set-to-nine inputs for use in BCD nine’s complement applications.

Decription :

Each of these monolithic counters contains four master-slave flip-flops and addtional gating to provide a divide-by-two counter and a three-stage binary counter for which the count cycle length is divide-by-five for the 90A and divide-by-eight for the 93A.

All of these counters have a gated zero reset and the 90A also has gated set-to-nine inputs for use in BCD nine’s complement applications.
