Description: This is a breakout board for the Texas Instruments TXB0104 module. 4-bit bidirectional voltage-level translator with automatic direction sensing Two separate configurable power-supply rails (Port A and B). The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB. Low power consumption, 5-andmu;A max ICC We have broken out each pin on this module for you to easily access both the A and B ports. Package Includes: 1x Module(5 Pack) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
