Product Summary
The 74LCX574TTR is a low voltage CMOS octal d-type flip flop with 3 state output non-inverting fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. The 74LCX574TTR is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs. The 74LCX574TTR 8 bit D-Type flip-flops are controlled by a clock input (CK) and an output enable input (OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs.
