74VCX16244/D
74VCX16244
Low-Voltage 1.8V/2.5V/3.3V
16-Bit Buffer
With 3.6 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
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 3.6 V.
The 74VCX16244 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.
