74LV8T245QWRKSRQ1

Overview

The SN74LV8T245-Q1 is an automotive-grade octal bus transceiver with three-state outputs and logic level shifting capabilities. It operates on a single supply voltage ranging from 1.65 V to 5.5 V, supporting data rates up to 150 Mbps at 3.3 V or 5 V. The device features enhanced input thresholds for up-translation (e.g., 1.2 V to 1.8 V) and 5.5 V tolerant inputs for down-translation. It includes AEC-Q100 qualification, HBM ESD Level 2, CDM Level C6, and latch-up performance exceeding 250 mA per JESD 17.

Feature Summary

• AEC-Q100 qualified for automotive applications with extended temperature range
• Single-supply voltage translator supporting both up and down translation
• Wettable flank QFN package available for improved inspection reliability

Applications

• Enable or disable a digital signal
• Eliminate slow or noisy input signals
• Hold a signal during controller reset
• Debounce a switch

Procurement Notes

Verify the specific package suffix matches the required form factor, as the WRKS designation indicates the wettable flank QFN variant. Confirm that the component meets the necessary AEC-Q100 grade requirements for the target automotive environment. Ensure design compliance with the specified absolute maximum ratings to prevent permanent damage during operation.

Selection Notes

Select this component when bidirectional octal data transfer with integrated voltage translation is required in automotive systems. It is suitable for interfacing between different CMOS logic families operating at varying supply voltages. Consider the thermal resistance metrics if high-density mounting is planned. Verify that the input transition rates meet system specifications to avoid excessive power consumption.

Part Context

This part belongs to Texas Instruments' LVxT family of logic devices designed for enhanced voltage level translation. The -Q1 suffix denotes automotive qualification, distinguishing it from standard commercial variants. It shares functional similarities with other octal bus transceivers but offers specific low-voltage input threshold enhancements for seamless interoperability across diverse voltage domains.

FAQ

How does the device handle voltage translation?

The device supports up-translation via reduced input thresholds and down-translation via 5.5 V tolerant inputs, with output levels referenced to the VCC supply.

What is the purpose of the wettable flanks?

Wettable flanks improve side solder wetting and allow for reliable visual inspection using automatic optical inspection (AOI) methods.
