The M74HC373 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with sub-micron silicon gate C2MOS technology. This 8-BIT D-Type latches is controlled by a latch enable input (LE) and output enable input (OE). While the LE input is held at a high level, the Q outputs will follow the data input. When the LE is taken low, the Q outputs will be latched at the logic level of D input data.
