M74HCT373 Octal D-Type Latch (3-State)

The M74HCT373 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.

While the OE input is at low level, the eight outputs will be in a normal logic state (high or low logic level) and when OE is in high level the outputs will be in a high impedance state.

The 3-State output configuration and the wide choice of outline make bus organized system simple.

All inputs are equipped with protection circuits against static discharge and transient excess voltage
