FXL4TD245UMX

The FXL4TD245 is a configurable 4-bit dual-voltage supply translator designed for both uni-directional and bi-directional voltage translation between two logic 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. This allows for bi-directional voltage translation 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. Internal power down control circuits place the device in 3-STATE if either VCC is removed. The Transmit/Receive (T/R(overline)) inputs independently determine the direction of data through each of the four bits. The OC(overline) input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXL4TD245 is designed so that the control pins (T/R(overline) and OE(overline)) are supplied by VCCA.

Key features

• Bi-directional interface between any 2 levels from 1.1V to 3.6V
• Fully configurable: inputs track VCC level

• 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(overline)n, OE(overline)) levels are referenced to VCCA voltage
