74LS192 Product details TheSN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate CountUp and Count Down Clocks are used and in either counting mode the circuits operate synchronously.

The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 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.

2022年10月26日 · 74LS192 Features. Synchronous Up/Down BCD Decade Counter, Count is Updated with Low-to-High Clock Transition; Synchronous Counting; High Speed up to 25MHz; Individual Preset Inputs; Standard TTL Switching Voltages; 74LS192 Specifications

The NTE74LS192 is a synchronous BCD reversible up/down counter in a 16 −Lead plastic DIP type. package having the complexity of 55 equivalent gates. 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.
