General Description
●The FXL4T245 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 VCCA level, and the B Port tracks the VCCB level. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for bidirectional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V.
●Features
●■ Bi-directional interface between any 2 levels from 1.1V to 3.6V
●■ Fully configurable, inputs track VCC level
●■ Non-preferential power-up sequencing; either VCC may be powered-up first
●■ No power-up sequencing required
●■ 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 inputs (T/R, OE) levels are referenced to VCCA 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)
