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.
