Part Number : 74LS191
Function : Synchronous 4-Bit Up/Down Counters With Up/Down Mode Control
Maker : Texas Instruments

Pinouts :
74LS191 datasheet

Description :

The '190, 'LS190, '191, and 'LS191 are synchronous, reversible up/down counters having a complexity of 58 equivalent gates. The '191 and 'LS191 are 4-bit binary counters and the '190 and 'LS190 are BCD counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic.
