Product specification
74F569
4-bit bidirectional binary synchronous counter (3-State)

1996 Jan 05
853–0376 16193
FEATURES
4-bit bidirectional counting – binary counter
Synchronous counting and loading
Look ahead carry capability for easy cascading
Preset capability for programmable operation
Master Reset (MR) overrides all other inputs
Synchronous Reset (SR) overrides counting and parallel loading
Clock Carry (CC) output to be used as a clock for flip-flops,
register and counters
3-State outputs for bus organized systems
DESCRIPTION
The 74F569 is a fully synchronous Up/Down binary counter. It
features preset capabilities for programmable operation, carry look
ahead for programmable operation, carry look ahead for easy
cascading, and U/D input to control the direction of counting. For
maximum flexibility there are both Synchronous and Master Reset
inputs as well as both Clocked Carry (CC) and Terminal Count (TC)
outputs. All state changes except Master Reset are initiated by
rising edge of the clock. A High signal on the Output Enable (OE)
input forces the output buffers into the high impedance state but
does not prevent counting, resetting or parallel loading.
