Bi-Directional Level Translator
IFB-10001
-
Easily connect Arduino or other 5V microcontrollers to ~3.3V sensors. Based on the TI TXB0108 auto-sensing, bi-directional level translator, this module provides access to all 8 channels of the TXB0108 and has a built-in 300mA LDO with 200mV max dropout voltage at full load. Regulated 3.3V output allows this single board to both interface withandpower 3.3V sensors. An important feature of this module is the ability to operate SPI and other digital lines (not including I2C) at high-speed, whereas the 'NXP level shifter' maxes out at 400kHz and resistor dividers fail much earlier. The TXB0108, integrated with the LP3981 LDO, provide a fast, reliable solution to mismatched interface voltages that exceeds the performance of other solutions.
