General Description

The FXLH42245 is a configurable dual-voltage-supply

translator designed for bi-directional voltage translation of

signals between two voltage levels. The device allows

translation between voltages as high as 3.6V to as low as

1.1V. The A Port tracks the V

tracks the V

supply voltage levels from 1.1V to 3.6V. This allows for bi-

directional voltage translation over a variety of voltage lev-

els: 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

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 FXLH42245 is designed so that

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