Description

The TXU0304-Q1 is a 4-bit, dual-supply, non-inverting direction-controlled voltage level translator. The Ax pins are referenced to the VCCA logic level, the OE pin can be referenced to either the VCCA or VCCB logic level, and the Bx pins are referenced to the VCCB logic level. Both the A port and the B port can accept an input voltage range of 1.1 V to 5.5 V. When OE is set high relative to either supply, direction-controlled data transmission from A to B or from B to A is enabled. When OE is set low, all output pins are in the high-impedance state. See the Device Functional Modes section for a summary of the control logic operation.

Features

AEC-Q100 qualified for automotive applications

Available in a wettable-flank QFN (WBQA) package

Fully configurable dual-rail design allows each port to operate over a 1.1-V to 5.5-V range

Supports rates up to 200 Mbps over the 3.3-V to 5.0-V range

Schmitt-trigger inputs enable slow and high-noise inputs

Inputs with integrated static pull-down resistors prevent channels from floating

High drive strength (up to 12 mA at 5 V)

Low power consumption

Maximum 3 µA (25°C)

Maximum 6 µA (–40°C to 125°C)

VCC isolation and VCC disconnect (Ioff-float) features

If either VCC input is below 100 mV or disconnected, all outputs are disabled and in the high-impedance state

Ioff supports partial-power-down mode operation

Control logic (OE) with VCC(MIN) circuitry allows control from either port A or port B

Pinout compatible with the TXB family of level translators

Available in other variants supporting common applications: TXU0104-Q1, TXU0204-Q1

Operating temperature range of –40°C to +125°C

Latch-up performance exceeds 100 mA per JESD 78, Class II

ESD protection exceeds JESD 22 specifications

2500-V human-body model

1500-V charged-device model
