DESCRIPTION

The 74HC244 is an advanced high-speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

silicon gate C2MOS technology.

G control input governs four BUS BUFFERs.

This device is designed to be used with 3 state

memory address drivers, etc.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
