74F569

4-Bit Bidirectional Counter with 3-STATE Outputs

General Description

Features

The 74F569 is a fully synchronous, reversible counter with

3-STATE outputs. The 74F569 is a binary counter, featur-

ing preset capability for programmable operation, carry loo-

kahead for easy cascading, and a U/D input to control the

direction of counting. For maximum flexibility there are both

synchronous and master asynchronous reset inputs as well

as both Clocked Carry (CC) and Terminal Count (TC) out-

puts. All state changes except Master Reset are initiated by

the rising edge of the clock. A HIGH signal on the Output

■ Synchronous counting and loading

■ Lookahead carry capability for easy cascading

■ Preset capability for programmable operation

■ 3-STATE outputs for bus organized systems

Enable (OE) input forces the output buffers into the high

impedance state but does not prevent counting, resetting

or parallel loading.
