The SN74LS192N is an up/down BCD decade (8421) 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.
It consists of 4 T flip flops and other gate circuits.There is a low effective asynchronous enabling preset (Load), which can preset input data (A/B/C/D) directly to the output port, and a high effective asynchronous zero clearing enabling control (Clear).Count Down and Count Up with additive and subtractive counting clock control input can realize continuous add-cycle counting or continuous subtractive cycle counting; Carry and Borrow with low output efficiency can realize multi-chip cascade expansion.
