HEF40193B Overview
The HEF40193B is a 4-bit synchronous up/down binary counter. The counter has 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 (TCU) and an active LOW terminal count-down (borrow) output (TCD).
