TXB0108DQSR
1 Features 3 Description

1 This 8-bit noninverting translator uses two separate • 1.2 V to 3.6 V on A Port and 1.65 V to 5.5 V on

configurable power-supply rails. The A port is B Port (VCCA ≤ VCCB)

designed to track VCCA. VCCA accepts any supply

TXB0108DQSR • VCC Isolation Feature – If Either VCC Input Is at voltage from 1.2 V to 3.6 V. The B port is designed to

GND, All Outputs Are in the High-Impedance track VCCB. VCCB accepts any supply voltage from

State 1.65 V to 5.5 V. This allows for universal low-voltage

TXB0108DQSR • OE bidirectional translation between any of the 1.2-V, Input Circuit Referenced to VCCA

1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. • Low Power Consumption, 4-μA Max ICC VCCA should not exceed VCCB.

TXB0108DQSR  • Ioff Supports Partial-Power-Down Mode Operation

When the output-enable (OE) input is low, all outputs

• Latch-Up Performance Exceeds 100 mA Per

are placed in the high-impedance state. JESD 78, Class II

The TXB0108 is designed so that the OE input circuit • ESD Protection Exceeds JESD 22

is supplied by VCCA.

– A Port

This device is fully specified for partial-power-down

– 2000-V Human-Body Model (A114-B) applications using Ioff. The Ioff circuitry disables the

– 1000-V Charged-Device Model (C101) outputs, preventing damaging current backflow

– B Port through the device when it is powered down.

– ±15-kV Human-Body Model (A114-B) To ensure the high-impedance state during power-up

– ±8-kV Human-Body Model (A114-B) or power-down, OE should be tied to GND through a

(YZP Package Only) pulldown resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the

– 1000-V Charged-Device Model (C101) driver.
