74ALVC16244
Low-Voltage 1.8/2.5/3.3 V
16-Bit Buffer
With 3.6 V–Tolerant Inputs and Outputs
(3–State, Non–Inverting)
The 74ALVC16244 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.
The 74ALVC16244 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.
• Designed for Low Voltage Operation: VCC = 1.65–3.6 V
• 3.6 V Tolerant Inputs and Outputs
• High Speed Operation: 3.0 ns max for 3.0 to 3.6 V

†To ensure the outputs activate in the 3–state condition, the output enable pins
should be connected to VCC through a pull–up resistor. The value of the resistor is
determined by the current sinking capability of the output connected to the OE pin.
