TXB0108 Description

Short technical summary and product information.

The Texas Instruments TXB0108 is an 8-bit noninverting, bidirectional voltage-level translator designed for universal low-voltage translation. It features two separate configurable power-supply rails, with the A port tracking VCCA (1.2 V to 3.6 V) and the B port tracking VCCB (1.65 V to 5.5 V). This allows for translation between various voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V.

Key features include auto-direction sensing, VCC isolation, and an output enable (OE) input referenced to VCCA. The device offers low power consumption with a maximum supply current of 4 mA and supports partial power-down applications using Ioff. It also provides robust ESD protection, exceeding JESD 22 standards with up to 2000 V for the Human-Body Model on the A port and ±15 kV on the B port.

The TXB0108 supports a maximum data rate of 100 Mbps with a propagation delay of 4 ns. It is available in various surface-mount packages including VFBGA, USON, VQFN, NFBGA, WQFN, TSSOP, DSBGA, and VSSOP, all with 20 pins.

This translator is suitable for applications requiring flexible voltage level shifting, such as interfacing microcontrollers with different voltage domains, or in systems utilizing GPIO, I2S, JTAG, PCM, SPI, and UART interfaces.
