Part Number : 74LS95
Function : Synchronous 4-Bit Binary Counter
Package : DIP, SO 14 Pin Type
Maker : Hitachi , Renesas Electronics
Pinouts : 
Description :
This 4-bit register features parallel and serial inputs, parallel outputs, mode control, and two clock inputs.
The register has three mode operation :
1. Parallel (broadside) load
