lev4 is a 4 channels bidirectional level shifter (5V / 3.3V) designed to solve voltage compatibility problems between devices, including I2C and SPI buses. lev4 is built around a Texas Instruments TXS0104E chip.
lev4 also provides a LDO regulator ( 3.3V, 500mA ) to supply power for external 3.3V devices.
Port A voltage : 1.65V ≤ VCCB ≤ 3.3V
4 level shifting channels for logical signals with internal "pull-up" 10 KOhms resistors. Channels are designed for classical "open-drain" applications but may also translate push-pull CMOS logic outputs .
Data rate in "open-drain" applications : 2 Mbps . A bit more if you dare.
1 integrated green LED ( voltage indicator light )
Connector 6 pins : 4 port B signals, 1 pin input power supply 5V, 1 pin GND. ( 6 pos. female header connector provided but not soldered)
Connector 8 pins : 4 port A signals, 2 pins output power supply 3.3V, 2 pins GND. ( 8 pos. female header connector provided but not soldered)
The level shifter is wired in "enable" mode by default. By removing (de-soldering or cutting) R2 resistor, the "enable/disable" mode may be remotely controlled by an external controller port. A 2 pins connector is ready for this application. In "disable" mode , all level shifter ports are placed in a high impedance state.
PCB: 50mm x 30mm
