74VCXH16244
Low-Voltage 1.8/2.5/3.3V
16-Bit Buffer
With 3.6 V–Tolerant Inputs and Outputs
(3–State, Non–Inverting)
The 74VCXH16244 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 over–voltage tolerant to 3.6 V.
The 74VCXH16244 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. The data inputs include active bushold
circuitry, eliminating the need for external pull–up resistors to hold
unused or floating inputs at a valid logic state.
Designed for Low Voltage Operation: V

NOTE:
To ensure the outputs activate in the 3–state condition, the output
enable pins should be connected to V
CC
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.
