Product Overview
The SN74AC564DBLE from Texas Instruments is an octal D-type flip-flop with 3-state outputs and inverting logic. It features edge-triggered operation with a clock (CLK) input and an output enable (OE) input. The device is designed for high-speed, low-power operation in 2V to 6V systems. Housed in a 20-pin SSOP package, it is ideal for bus-oriented applications requiring high drive capability and noise immunity.
