TXB0104PWR is a 4-channel bidirectional auto level shifter from TI, supporting 1.2V~5.5V dual voltage domains with push-pull output topology, free of latch-up risk. Optimized for SPI, UART, parallel GPIO low-speed buses. Packaged in TSSOP14 SMD, industrial range -40℃~+85℃, integrated isolation impedance to suppress bus reflection for multi-voltage embedded systems.
1. Dedicated push-pull topology eliminates ringing and latch-up for high-speed digital signals
2. 4 integrated lanes realize multi-channel GPIO/SPI parallel translation with single IC
3. Ultra-wide voltage compatibility for legacy 5V devices and modern 1.2V low-power chips
4. Auto signal direction detection without DIR pin, simplified firmware development
5. On-chip ESD protection for stable operation in industrial EMI environments
Typical Applications
1. Voltage matching between STM32/PIC MCU and 5V peripherals (relays, LEDs, legacy sensors)
2. Signal bridging between FPGA IO and 3.3V Ethernet PHY / memory ICs
3. Mixed-signal translation for automatic test fixtures & multi-channel DAQ boards
4. Heterogeneous voltage systems for smart home main controllers & EV charger auxiliary boards
