The ‘LS169B and ‘S169 are 4-bit binary counters. The 74LS169 features an internal carry look-ahead for cascading in high speed counting applications. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instru..

The 74LS181 IC is an arithmetic logic unit / function generator IC that has a complexity of 75 congruent gates on a monolithic IC chip. These circuits perform 16 binary arithmetic operations on two 4-bit words. These operations are selected by the four function-select lines (S0, S1, S2, S3) and incl..

The 74LS193 is an UP/DOWN DIP-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. Separate Terminal Count Up and Terminal Count D..

The 74LS194 bidirectional shift register is designed to incorporate virtually all of the features a system designer may want in a shift register; they feature parallel inputs, parallel outputs, right-shift and left-shift serial inputs, operating-mode-control inputs, and a direct overriding clear lin..
