LOW–VOLTAGE 1.8/2.5/3.3V
16–BIT BUFFER
The MC74VCX162244 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.
WITH 26Ω SERIES RESISTORS
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 MC74VCX162244 is nibble controlled with each nibble functioning
identically, but independently. It is designed with 26Ω series resistors in
each of the outputs to reduce noise. 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.
