SN74LS191 Product details

Description

The LS190 is a synchronous Up / Down BCD Decade Counter and the LS191 is a synchronous Up / Down 4-Bit Binary Counter.

The operating modes of the LS190 decade counter and the LS191 binary counter are identical, with the only difference being the count sequences as noted in the state diagrams.

Features

ditions VCC = 5.0 V CL = 15 pF Test Conditions VCC = 5.0 V.
