MC74VCX16244

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Low-Voltage 1.8/2.5/3.3V 16-Bit Buffer With 3.6V-Tolerant Inputs and Outputs (3-State, Non-Inverting) MC74VCX16244 VCX LOW–VOLTAGE 1.8/2.5/3.3V 16–BIT BUFFER The MC74VCX16244 is an advanced performance, non–inverting 16–bit buffer. It is designed for very high–speed, very low–power operation in 1.8V, 2.5V or 3.3V systems. When operating at 2.5V (or 1.8V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3V busses. It is guaranteed to be over–voltage tolerant to 3.6V. The MC74VCX16244 is nibble controlled with each nibble functioning identically, but independently. The control pins may be tied together to obtain full 16–bit operation. The 3–state outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are on. When OEn is HIGH, the outputs are in the high impedance state.
