1 Features 3 Description

Voltage-level translators address the challenges 1• Qualified for Automotive Applications

posed by simultaneous use of different supply-voltage

TXB0104QPWRQ1 • AEC-Q100 Qualified With the Following Results levels on the same circuit board. This 4-bit non–

Device Temperature Grade 1: –40°C to inverting translator uses two separate configurable

+125°C Ambient Operating Temperature power-supply rails. The A port is designed to track

Range VCCA. VCCA accepts any supply voltage from 1.2 V to

3.6 V. The B port is designed to track VCCB. VCCB • 1.2 V to 3.6 V on A Port and 1.65 V to 5.5 V on B

accepts any supply voltage from 1.65 V to 5.5 V. This Port (VCCA ≤ VCCB)

allows for universal low-voltage bidirectional

TXB0104QPWRQ1 • VCC Isolation Feature – If Either VCC Input is at translation between any of the 1.2-V, 1.5-V, 1.8-V,

GND, All Outputs are in the High-Impedance State 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not

TXB0104QPWRQ1 • OE Input Circuit Referenced to V exceed VCCB. CCA

• 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. To ensure

the high-impedance state during power up or power JESD 78, Class II

down, OE should be tied to GND through a pulldown

• ESD Protection Exceeds JESD 22 resistor; the minimum value of the resistor is

– A port determined by the current-sourcing capability of the

– ±2500-V Human-Body Model driver. (A114-B)

– ±1000-V Charged-Device Model (C101) The TXB0104 is designed so that the OE input circuit

– B port is supplied by VCCA.

– ±15000-V Human-Body Model (A114-B) This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the – ±1000-V Charged-Device Model (C101)

outputs, preventing damaging current backflow

through the device when it is powered down. 2 Applications
