74VCX162838
Low Voltage 16-Bit Selectable Register/Buffer
with 3.6V Tolerant Inputs and Outputs
and 26
Series Resistors in the Outputs
General Description
The VCX162838 contains sixteen non-inverting selectable
buffered or registered paths. The device can be configured
to operate in a registered, or flow through buffer mode by
utilizing the register enable (REGE) and Clock (CP) sig-
nals. The device operates in a 16-bit word wide mode. All
outputs can be placed into 3-State through the use of the
OE pin. These devices are ideally suited for buffered or
registered 168 pin and 200 pin SDRAM DIMM memory
modules.
The 74VCX162838 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The VCX162838 is also designed with 26
series resistors
in the outputs. This design reduces line noise in applica-
tions such as memory address drivers, clock drivers, and
bus transceivers/transmitters.
The 74VCX162838 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.
