LEVEL TRANSLATOR

The FXLH1T45 is a single bit 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 (T/R) input determines the direction of data flow through the device. The FXLH1T45 is designed so that the control pin (T/R) is 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
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Control input (T/R) levels are referenced to VCCA voltage
