Features & Applications

The FXL4T245BQX 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 3.6 V to as low as 1.1 V.

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 1.1 V to 3.6 V. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. 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 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 3-STATE condition. The FXL4T245 is designed so that the control pins (T/R# and OE#) are supplied by VCCA.


  • Bi-directional interface between any 2 levels from 1.1 V to 3.6 V
  • 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 (2.5 mm x 3.0 mm) package
  • ESD protection exceeds:
  • 4 kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7)
  • 8 kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7)
  • 1 kV CDM ESD (per ESD STM 5.3)
  • 200 V MM ESD (per JESD22-A115 & ESD STM5.2)
