FXL5T244
Low Voltage Dual Supply 5-Bit Signal Translator
with Configurable Voltage Supplies
and Signal Levels and 3-STATE Outputs
General Description
Features
■ One-way (unidirectional) translation between any
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 VCCI
2 levels from 1.1V to 3.6V
■ Fully configurable, inputs and outputs track respective
VCC levels
■ Non-preferential power-up sequencing; either VCC may
be powered-up first
level, and Y Outputs track the VCCO 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.
■ Outputs remain in 3-STATE until active VCC level is
reached
■ Outputs switch to 3-STATE if either VCC is at GND
The device remains in 3-STATE until both VCCs reach
active levels allowing either VCC to be powered-up first.
■ Power-off protection
■ Control input (OE) level is referenced to VCCI voltage
The device also contains power down control circuits that
place the device in 3-STATE if either VCC is removed. The

OE input, when HIGH, disables the outputs by placing
them in 3-STATE condition.
■ ESD protection exceeds:
• 4kV HBM ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
• 8kV HBM I/O to GND ESD
(per JESD22-A114 & Mil Std 883e 3015.7)
• 1kV CDM ESD (per ESD STM 5.3)
• 200V MM ESD (per JESD22-A115 & ESD STM5.2)
