M74HC563 Octal D-Type Latch (3-State/Inv.)

The M74HC563 is an high speed CMOS OCTAL LATCH WITH 3-STATE OUTPUTS fabricated with 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 inversely. When the LE is taken, the Q outputs will be latched inversely 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 while 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
