74LVCH16245ADGG-QJ

Overview

The Nexperia 74LVCH16245ADGG-QJ is a 16-bit bus transceiver with direction pins and 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage range of 1.2 V to 3.6 V with overvoltage tolerant inputs up to 5.5 V. The device supports two 8-bit or one 16-bit configuration using MULTIBYTE flow-through architecture. It features Schmitt-trigger inputs, IOFF circuitry for partial power-down, and bus hold functionality specific to the LVCH variant.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Bus hold feature on data inputs eliminates need for external pull-up resistors
• Schmitt-trigger action provides tolerance for slower input rise and fall times

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down applications requiring backflow prevention
• Automotive electronic systems

Procurement Notes

Verify the exact suffix against official Nexperia documentation, as ordering codes determine package type and temperature range. Confirm AEC-Q100 Grade 1 qualification status for automotive compliance. Ensure the selected variant matches the required TSSOP48 package dimensions and lead pitch specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring 16-bit bidirectional data transfer in mixed-voltage environments. The LVCH variant is preferred if bus hold functionality is needed to stabilize unused inputs without external components. Verify that the operating temperature range meets the -40 °C to +125 °C requirement for the target application environment.

Part Context

This part belongs to the Nexperia 74LVC/LVCH16245A-Q100 family of 16-bit bus transceivers. It shares functional characteristics with the standard 74LVC16245A but includes specific automotive qualification and LVCH enhancements like bus hold. The ADGG suffix indicates the TSSOP48 plastic thin shrink small outline package.

Replacement Considerations

The 74LVC16245ADGG-Q100 serves as a direct non-bus-hold alternative within the same automotive-qualified family.
