Description

This is a break-out board for TXU0304 level shifter, with top side silkscreen for SPI bus.

 

Connect the middle pin (ENA, enable) to one of the voltage sources to enable the level shifter.  When ENA is pulled to ground, all outputs are in high impedance (high-Z) state.

 

The + pin is the logic level voltage for either side.  TXU0304-Q1 supports either side between 1.1V and 5.5V.

 

When manufacturing, ask the manufacturer to put their markings anywhere on the bottom side, where the IC and the two 0.1µF bypass capacitors are.
