LEVEL TRANSLATOR

The FXL2TD245 is a configurable 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 inputs independently determine the direction of data through each of the two bits. The OE input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXL2TD245 is designed so that the control pins (T/R and OE) are supplied by VCCA.

• 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
• 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/Rn, OE) levels are referenced to VCCA voltage
