74F191
Overview
The 74F191 is a 4-bit binary counter. It contains four edge-triggered master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operations.
- High speed -125MHz typical fMAX
- Synchronous, reversible counting
- 4-Bit binary
- Asynchronous parallel load capability
- Cascadable without external logic
- Single up/down control input
