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
CCA
level, and the
B Port tracks the V
CCB
level. 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
CC
s reach
active levels allowing either V
CC
to be powered-up first.
Internal power down control circuits 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 FXL2T245 is designed so that the
control pins (T/R and OE) are supplied by V
CCA
.
