DESCRIPTION The 74LVQ244 is a low voltage CMOS OCTAL BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS

technology. It is ideal for low power and low noise 3.3V applications. G control output governs four BUS BUFFERs. This device is designed to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
