The 40192 device is a 4-bit synchronous up/down decade counter with a count-up clock
input (CPU), a count-down clock input (CPD), an asynchronous parallel load input (PL
),
four parallel data inputs (P0 to P3), an asynchronous master reset input (MR), four counter
outputs (O0 to O3), an active LOW terminal count-up (carry) output (TC
U) and an active
LOW terminal count-down (borrow) output (TC
D).
