Package

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

B port tracks the V

accept supply voltage levels from 1.1V to 3.6V. This

allows for bi-directional 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

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