FXL5T244

Low Voltage Dual Supply 5-Bit Signal Translator

with Configurable Voltage Supplies

and Signal Levels and 3-STATE Outputs

General Description

The FXL5T244 is a configurable dual-voltage-supply trans-

lator designed for one-way (unidirectional) voltage transla-

tion of signals between two voltage levels. The device

allows translation between voltages as high as 3.6V to as

low as 1.1V. A Inputs and the OE Control Pin track the V

level, and Y Outputs track the V

outputs are designed to accept supply voltage levels from

1.1V to 3.6V. This allows for unidirectional voltage transla-

tion over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V,

and 3.3V.

The device remains in 3-STATE until both V

active levels allowing either V

The device also contains power down control circuits that

place the device in 3-STATE if either V

OE input, when HIGH, disables the outputs by placing
