TXS0104EPWR is a 4-channel open-drain dedicated level shifter by TI, optimized for I2C/SMBus open-drain buses, supporting translation from 1.2V~3.3V low domain to 1.8V~5.5V high domain in TSSOP14 package. No external pull-up resistors required with auto open-drain impedance matching, industrial range -40~+85℃, dedicated for cross-voltage I2C bus translation.

1. Channels: 4 bidirectional open-drain lanes 2. VCCA=1.2~3.3V, VCCB=1.8~5.5V 3. Max I2C Speed: 400kHz Fast-mode 4. Package: TSSOP-14 5. Temp Range: -40℃ ~ +85℃ 6. Bus Compliance: SMBus, multi-master I2C

1. Natively optimized for open-drain I2C, eliminates external pull-ups and simplifies BOM 2. Auto bidirectional signal detection without multi-master I2C communication collision 3. Low quiescent power for long-term stable operation of battery-powered sensor modules 4. 4 integrated lanes supporting 4 independent groups of I2C peripherals per chip 5. On-chip noise suppression prevents packet loss under heavy industrial EMI

1. Cross-voltage bridging for I2C EEPROM, temperature/humidity sensors, ADC modules 2. Multi-channel I2C sensor acquisition boards for industrial PLCs 3. Low-power I2C signal translation for portable medical testers 4. I2C bus level matching for automotive interior instruments & lamp control units --- # 二、以太网PHY/交换芯片
