74F779 - 8-Bit Bidirectional Binary Counter

General Description

The 74F779 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

  • carry lookahead for easy cascading. All state changes are initiated by the rising edge of the clock. Features s Multiplexed 3-STATE I/O ports s Built-in lookahead carry capability s Count frequency 100 MHz typ s Supply current 80 mA typ s Available in SOIC (300 mil only) Ordering Code: Order Number 74F779SC 74F779PC Package Number M16B N16E Package.
