74LVC16245AEV-Q10Y

Overview

The Nexperia 74LVC16245AEV-Q10Y is a 16-bit bus transceiver with 3-state outputs, qualified to AEC-Q100 Grade 1. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. It operates from -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action provides tolerance for slower input rise and fall times
• Inputs accept voltages up to 5.5 V for mixed 3.3 V and 5 V environments

Applications

• Automotive electronic systems requiring bidirectional level translation
• Mixed voltage environments interfacing 3.3 V and 5 V devices
• Partial power-down applications utilizing IOFF functionality

Procurement Notes

Verify the specific package type against the ordering information table, as the EV suffix indicates a variant not listed in the primary SOT362-1 or SOT480-1 packages. Confirm the exact temperature range and electrical characteristics match the datasheet specifications for the intended application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring automotive-grade reliability and bidirectional data transmission between different voltage domains. Ensure the system design accommodates the specified supply voltage range and utilizes the direction control pins appropriately for flow-through architecture implementation.

Part Context

This part belongs to the 74LVC/LVCH16245A-Q100 family of 16-bit bus transceivers. It shares functional similarities with other members like the 74LVC16245ADGG-Q100 but may differ in physical packaging or specific manufacturing revisions. The Q100 suffix denotes automotive qualification.

Replacement Considerations

Direct substitutes include 74LVC16245ADGG-Q100 and 74LVCH16245ADGG-Q100. Verify pinout compatibility and package dimensions when replacing the AEV variant with these standard TSSOP48 versions.
