Product Description


Product Details


This noninverting 8-bit translator features two individually configurable power rails. The A port's purpose is to monitor VCCA. Any source voltage between 1.2 and 3.6 volts is supported by VCCA. The B port is used to monitor the VCCB. Any source voltage between 1.65 V and 5.5 V is acceptable to VCCB. This permits bidirectional universal low-voltage translation between any of the voltage nodes 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V. The value of VCCA shall not be more than the value of VCCB.

All outputs become high-impedance when the output-enable (OE) input is low. The OE input circuit of the TXB0108 is powered by VCCA.


This device is designed entirely for Ioff-based partial-power-down applications. The Ioff circuitry disables the outputs when the device is switched off, eliminating dangerous current backflow through the device.

Connect OE to GND through a pulldown resistor to maintain the high-impedance situation during power-up or power-down; the minimum value of the resistor is set by the driver's current-sourcing capabilities.



• 1.2 V to 3.6 V on A Port and 1.65 V to 5.5 V on B Port (VCCA ≤ VCCB)
• VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
• OE Input Circuit Referenced to VCCA
• Low Power Consumption, 4-μA Max ICC
• Ioff Supports Partial-Power-Down Mode Operation
• Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
• ESD Protection Exceeds JESD 22
