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
