The 74LVX573 is a low voltage CMOS OCTAL D-TYPE LATCH with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power, battery operated and low noise 3.3V applications. This 8 bit D-Type latch is controlled by a latch enable input (LE) and an output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input precisely.
