74F1779 - 8-bit bidirectional binary counter

General Description

The 74F1779 is a fully synchronous 8-stage up/down counter with multiplexed 3-State I/O ports for bus-oriented applications.

All control functions (hold, count up, count down, synchronous load) are controlled by two mode pins (S0, S1).

Key Features

  • Multiplexed 3-State I/O ports for bus oriented.
