74VCX162835
Low Voltage 18-Bit Universal Bus Driver with
3.6V Tolerant Inputs/Outputs
and 26
Series Resistors in Outputs
General Description
The VCX162835 low voltage 18-bit universal bus driver
combines D-type latches and D-type flip-flops to allow data
flow in transparent, latched and clocked modes.
Data flow is controlled by output-enable (OE), latch-enable
(LE), and clock (CLK) inputs. The device operates in
Transparent Mode when LE is held HIGH. The device
operates in clocked mode when LE is LOW and CLK is tog-
gled. Data transfers from the Inputs (I
n
) to Outputs (O
n
) on
a Positive Edge Transition of the Clock. When OE is LOW,
the output data is enabled. When OE is HIGH the output
port is in a high impedance state.
The VCX162835 is designed with 26
series resistors in
the outputs. This design reduces noise in applications such
as memory address drivers, clock drivers, and bus trans-
ceivers/transmitters.
The 74VCX162835 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O capability up to 3.6V.
The 74VCX162835 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 pulldown resistor; the minimum
value of the resistor is determined by the current sourcing capability of the
driver.
