FXL2T245

Low Voltage Dual Supply 2-Bit Signal Translator

with Configurable Voltage Supplies

and Signal Levels and 3-STATE Outputs

General Description

The FXL2T245 is a configurable dual-voltage-supply trans-

lator designed 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

B Port tracks the V

voltage translation 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

Internal power down control circuits place the device in

3-STATE if either V

The Transmit/Receive (T/R) input determines the direction

of data flow through the device. The OE input, when HIGH,

disables both the A and B Ports by placing them in a

3-STATE condition. The FXL2T245 is designed so that the

control pins (T/R and OE) are supplied by V
