74HCT193, 74HC193, Presettable synchronous 4-bit binary up/down counter
The 74HC193; 74HCT193 is a 4-bit synchronous binary up/down counter.
Separate up/down clocks, CPU and CPD respectively, simplify operation.
The outputs change state synchronously with the LOW-to-HIGH transition of either clock input.
If the CPU clock is pulsed while CPD is held HIGH, the device will
