74ALVC162839
Low Voltage 20-Bit Selectable Register/Buffer
with 3.6V Tolerant Inputs/Outputs
and 26
Series Resistors in the Outputs
General Description
The ALVC162839 contains twenty 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 (CLK) sig-
nals. The device operates in a 20-bit word wide mode. All
outputs can be placed into 3-STATE through use of the OE
pin. These devices are ideally suited for buffered or regis-
tered 168 pin and 200 pin SDRAM DIMM memory mod-
ules.
The 74ALVC162839 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74ALVC162839 is also designed with 26
series
resistors in the outputs. This design reduces line noise in
applications such as memory address drivers, clock driv-
ers, and bus transceivers/transmitters.
The 74ALVC162839 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.
