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 VCCI

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.

The device remains in 3-STATE until both VCCs reach

active levels allowing either VCC to be powered-up first.

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.

Features

■ One-way (unidirectional) translation between any

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

■ Outputs remain in 3-STATE until active VCC level is

reached

■ Outputs switch to 3-STATE if either VCC is at GND

■ Power-off protection

■ Control input (OE) level is referenced to VCCI voltage

■ Packaged in 14-terminal DQFN (2.5mm x 3.0mm)

package

■ 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)
