Product data sheet
1. 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.
2. Features and benefits
„ Synchronous counting and loading
„ Built-in look-ahead carry capability
„ Count frequency 115 MHz (typical)
„ Supply current 95 mA (typical)
