Low Voltage 18-Bit Universal Bus Driver

with 3.6V Tolerant Inputs and Outputs

General Description

The VCX16835 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.

Features

■ Compatible with PC100 DIMM module specifications

■ 1.65V–3.6V V_CCspecifications provided

■ 3.6V tolerant inputs and outputs

■ t_PD(CP to O_n)

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 Ouputs (O_n) on a

4.2ns max for 3.0V to 3.6V V_CC

5.2ns max for 2.3V to 2.7V V_CC

9.2ns max for 1.65V to 1.95V V_CC

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.

■ Power-down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ Static Drive (I_OH/I_OL

)

The 74VCX16835 is designed for low voltage (1.65V to

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

±24mA @ 3.0V

±18mA @ 2.3V

±6mA @ 1.65V

The 74VCX16835 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

■ Latchup 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_CC(OE to GND) through a pulldown resistor;

the minimum value of the resistor is determined by the current sourcing

capability of the driver.
