74LVC244A Low Voltage CMOS Octal Bus Buffer (3-State) Advenced Performance

The 74LVC244A is a low voltage CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for 1.65 to 3.6 VCC operations and low power and low noise applications.

It can be interfaced to 5V signal environment for inputs in mixed 3.3/5V system.

G control output governs four BUS BUFFERs.

This device is designed to be used with 3 state memory address drivers, etc.

It has more speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
