74VCX16373
Low Voltage 16-Bit Transparent Latch
with 3.6V Tolerant Inputs and Outputs
General Description
The VCX16373 contains sixteen non-inverting latches with
3-STATE outputs and is intended for bus oriented applica-
tions. The device is byte controlled. The flip-flops appear to
be transparent to the data when the Latch Enable (LE) is
HIGH. When LE is LOW, the data that meets the setup time
is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH, the outputs are in
a high impedance state.
The 74VCX16373 is designed for low voltage (1.4V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74VCX16373 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Note 1:
To ensure the high-impedance state during power up or power
down, OE should be tied to V
CC
through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
