FXLA104

Low-Voltage Dual-Supply 4-Bit Voltage Translator with

Configurable Voltage Supplies and Signal Levels,

3-State Outputs, and Auto Direction Sensing

Features

Description

Bi-Directional Interface between Two Levels:

from 1.1V to 3.6V

The FXLA104 is a configurable dual-voltage supply

translator for both uni-directional and bi-directional

voltage translation between two logic levels. The device

allows translation between voltages as high as 3.6V to

as low as 1.1V. The A port tracks the V_CCAlevel and the

B port tracks the V_CCBlevel. This allows for bi-directional

voltage translation over a variety of voltage levels: 1.2V,

1.5V, 1.8V, 2.5V, and 3.3V.

Fully Configurable: Inputs and Outputs Track V_CC

Non-Preferential Power-Up; Either V_CCMay Be

Powered Up First

Outputs Switch to 3-State if Either V_CCis at GND

Power-Off Protection

The device remains in three-state as long as either

Bus-Hold on Data Inputs Eliminates the Need for

Pull-Up Resistors; Do Not Use Pull-Up Resistors on

A or B Ports

V_CC=0V, allowing either V_CCto be powered up first.

Internal power-down control circuits place the device in

3-state if either V_CCis removed.

Control Input (/OE) Referenced to V_CCAVoltage

The /OE input, when HIGH, disables both the A and B

ports by placing them in a 3-state condition. The /OE

Available in 16-Terminal UMLP (1.8mm x 2.6mm)

and 12-Terminal, Quad UMLP, 1.8 x 1.8mm

Packages

input is supplied by V_CCA

The FXLA104 supports bi-directional translation without

the need for a direction control pin. The two ports of the

device have auto-direction sense capability. Either port

may sense an input signal and transfer it as an output

signal to the other port.

Direction Control Not Necessary

100Mbps Throughput when Translating Between

1.8V and 2.5V

ESD Protection Exceeds:

- 8kV HBM (per JESD22-A114 & Mil Std 883e

3015.7)

- 2kV CDM (per ESD STM 5.3)

Applications

Cell Phone, PDA, Digital Camera, Portable GPS
