M74HCT244 Octal Bus Buffer (3-State)

The 74HCT244 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology.

G control input governs four BUS BUFFERs.

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