Low-Voltage 1.8/2.5/3.3V
16-Bit Buffer
With 26Series Resistors
3.6V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
MC74VCX162244
VCX
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.
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 26series 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.
Designed for Low Voltage Operation: VCC = 1.8–3.6V
3.6V Tolerant Inputs and Outputs
High Speed Operation: 3.3ns max for 3.0 to 3.6V
3.8ns max for 2.3 to 2.7V
5.7ns max for 1.8V
Static Drive:
±12mA Drive at 3.0V
±8mA Drive at 2.3V
±4mA Drive at 1.8V
Supports Live Insertion and Withdrawal
IOFF Specification Guarantees High Impedance When VCC = 0V
Near Zero Static Supply Current in All Three Logic States (20µA)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds ±300mA
ESD Performance: Human Body Model >2000V; Machine Model >200V
