General description
The 74F269 is a fully synchronous 8-stage up/down counter featuring a preset capability
for programmable operation, carry look-ahead for easy cascading and a U/D input to
control the direction of counting. All state changes, whether in counting or parallel loading,
are initiated by the rising edge of the clock.
