74F193 Description
The 74F193 is a 4-bit synchronous up/down counter in the binary mode. 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.
74F193 Key Features
- Synchronous reversible 4-bit counting
- Asynchronous parallel load capability
- Asynchronous reset (clear)
- Cascadable without external logic
74F193 Applications
- D3) is loaded into the counter and appears on the outputs regardless of the conditions of the clock inputs when the Parallel Load (PL) input is Low. A High leve
