FXLH42245
Low Voltage Dual Supply 8-Bit Signal Translator
with Configurable Voltage Supplies and
Bushold Data Inputs and 3-STATE Outputs and
26
Series Resistors in the B Port Outputs
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
CCA
level, and the B Port
tracks the V
CCB
level. Both ports are designed to accept
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
CC
s reach
active levels allowing either V
CC
to be powered-up first.
The device also contains power down control circuits that
place the device in 3-STATE if either V
CC
is removed.
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
CCA
.
