The 74VCX16244 is an advanced performance, non?inverting 16?bit buffer. It is designed for very high?speed, very low?power operation in 1.8 V, 2.5 V or 3.3 V systems. When operating at 2.5 V (or 1.8 V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6V.
