00 — Overview

What the TXB0108 family does

The TXB0108 is an 8-bit bidirectional voltage-level translator featuring auto-direction sensing and ±15kV ESD protection. It supports translation between 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V nodes with a maximum supply current of 4μA. The device includes a VCC isolation feature that places outputs in a high-impedance state when the OE input is low. It supports partial-power-down mode operation and latch-up performance exceeding 100mA per JESD 78, Class II. Engineers typically use this component in handheld devices, smartphones, tablets, desktop PCs, and processor peripherals to interface between different voltage domains.
