74F17798-bit bidirectional binary counter (3-State)

FEA TURES

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

•Built-in look-ahead carry capability

•Center power pins to reduce effects of package inductance

•Count frequency 145MHz typical

•Supply current 90mA typical

•See 74F269 for 24-pin separate I/O port version

•See 74F579 for 20-pin version

•See 74F779 for 16-pin version with abbreviated function table

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). The device also features carry look-ahead for easy cascading. All state changes are initiated by the rising edge of the clock. When CET held in their current state and TC recommended for use as a clock or asynchronous reset due to the possibility of decoding spikes.

The 74F1779 differs from 74F779 in that it has an additional hold mode as described in the Function Table.
