FXL5T244
Low Voltage Dual Supply 5-Bit Signal Translator
with Configurable Voltage Supplies
and Signal Levels and 3-STATE Outputs
General Description
The FXL5T244 is a configurable dual-voltage-supply trans-
lator designed for one-way (unidirectional) voltage transla-
tion of signals between two voltage levels. The device
allows translation between voltages as high as 3.6V to as
low as 1.1V. A Inputs and the OE Control Pin track the V_CCI
level, and Y Outputs track the V_CCO level. Both inputs and
outputs are designed to accept supply voltage levels from
1.1V to 3.6V. This allows for unidirectional voltage transla-
tion 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_CCs 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
OE input, when HIGH, disables the outputs by placing
them in 3-STATE condition.
Features
s One-way (unidirectional) translation between any
2 levels from 1.1V to 3.6V
s Fully configurable, inputs and outputs track respective
V_CC levels
s Non-preferential power-up sequencing; either V_CC may
be powered-up first
s Outputs remain in 3-STATE until active V_CC level is
reached
s Outputs switch to 3-STATE if either V_CC is at GND
s Power-off protection
s Control input (OE) level is referenced to V_CCI voltage
s Packaged in 14-terminal DQFN (2.5mm x 3.0mm)
package
