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.
