SN74LS193N 4-Bit Binary Up / Down Counter IC - DIP-16

Datasheet

The SN74LS193N is an UP/DOWN BCD Decade (8421) Counter and the SN74LS193N is an UP/DOWN MODULO-16 Binary Counter. Separate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs.
