FXL4T245BQX - Low Voltage Dual Supply 4-Bit Signal Translator

With configurable voltage supplies, signal levels and 3-STATE outputs from onsemi

FXL4T245BQX - Low Voltage Dual Supply 4-Bit Signal Translatoronsemi 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 3.6 V to as low as 1.1 V. The A port tracks the VCC(A) level and the B port tracks the VCC(B) level. Both ports are designed to accept supply voltage levels from 1.1 V to 3.6 V. This allows for bidirectional 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 VCC(S) 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.

Connection diagram

  • 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 input levels (T/R, OE) are referenced to VCC(A) voltage
  • Packaged in 14-terminal DQFN (2.5 mm x 3.0 mm) package
