Outputs (3-State, Non-Inverting)
MC74VCX16244
VCX
The MC74VCX16244 is an advanced performance, nonâinverting
16âbit buffer. It is designed for very highâspeed, very lowâpower
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 overâvoltage 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 16âbit operation. The 3âstate 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.
