74HC193 (Presettable Synchronous Counter) DC Barrel Jack The output of the sensorIntroduction : 74HC193 is a 4 bit synchronous binary up down counter. Separate up downclocks, CPU and CPD respectively, simplify operation. The outputs change state synchronouslywith the LOW to HIGH transition of either clock input. If the CPU clock is pulsed while CPD is heldHIGH, the device will count up. If the CPD clock is pulsed while CPU is held HIGH, the device willcount down. Only one clock input can be held HIGH at any time to guarantee
