74VCX162839
Low Voltage 20-Bit Selectable Register/Buffer with
3.6V Tolerant Inputs and Outputs
and 26Series Resistors in the Outputs
General Description
The VCX162839 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 (CP) 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 74VCX162839 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O compatibility up to 3.6V.
The 74VCX162839 is also designed with 26series resis-
tors in the outputs. This design reduces line noise in appli-
cations such as memory address drivers, clock drivers, and
bus transceivers/transmitters.
The 74VCX162839 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

9.8 ns max for 1.65V to 1.95V VCC
s Power-off high impedance inputs and outputs
s Supports live insertion and withdrawal (Note 1)
s Static Drive (IOH/IOL)
±12 mA @ 3.0V VCC
±8 mA @ 2.3V VCC
±3 mA @ 1.65V VCC
s Uses patented noise/EMI reduction circuitry
s Latch-up performance exceeds 300 mA
s ESD performance:

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

Functional Description
The 74VCX162839 consists of twenty selectable non-
inverting buffers or registers with word wide controls. Mode
functionality is selected through operation of the CP and
REGE pin as shown by the truth table. When REGE is held
at a logic “1” the device operates as a 20-bit register. Data
is transferred from In to On on the rising edge of the CP pin.
When the REGE pin is held at a logic “0” the device oper-
ates in a flow through mode and data propagates directly
from the In to the On outputs. All outputs can be 3-stated by
holding the OE pin at a logic “1.”
