74VCX16839

Low Voltage 20-Bit Selectable Register/Buffer with 3.6V

Tolerant Inputs and Outputs

General Description

Features

■ Compatible with PC100 and PC133 DIMM module

The VCX16839 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.

specifications

■ 1.65V–3.6V V_CCsupply operation

■ 3.6V tolerant inputs and outputs

■ t_PD(CP to O_n)

3.2 ns max for 3.0V to 3.6V V_CC

4.4 ns max for 2.3V to 2.7V V_CC

8.8 ns max for 1.65V to 1.95V V_CC

The 74VCX16839 is designed for low voltage (1.65V to

3.6V) V_CCapplications with I/O compatibility up to 3.6V.

■ Power-off high impedance inputs and outputs

■ Supports live insertion and withdrawal (Note 1)

The 74VCX16839 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

■ Static Drive (I_OH/I_OL

)

±24 mA @ 3.0V V_CC

±18 mA @ 2.3V V_CC

±6 mA @ 1.65V V_CC

■ Uses patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 300 mA

■ ESD performance:

Human body model > 2000V

Machine model > 200V

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to V

through a pull-up resistor; the minimum

value of the resistor is determined by the current-sourcing capability of the

driver.
