74LVC245AD-Q100J

Overview

The Nexperia 74LVC245AD-Q100J is an automotive-qualified octal bus transceiver with 3-state outputs, designed for bidirectional data transmission. It operates within a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant up to 5.5 V, enabling direct interfacing with 5 V logic in mixed-voltage environments. The device includes Schmitt trigger inputs for noise immunity and IOFF circuitry to prevent backflow current during partial power-down states. Packaged in a 20-lead SOIC (SOT163-1), it supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry enables safe partial power-down mode operation
• Schmitt trigger inputs provide tolerance for slow signal transitions
• Overvoltage tolerant inputs allow direct interface with 5 V logic

Applications

• Mixed 3.3 V and 5 V logic level translation
• Bidirectional data bus driving
• Buffering memory address registers

Procurement Notes

Verify the specific suffix 'Q100J' against official Nexperia documentation to confirm package marking and reel specifications. Ensure the procurement channel provides traceability to the original manufacturer. Confirm that the delivered components match the SOT163-1 package outline dimensions specified in the datasheet.

Selection Notes

Select this component when designing systems requiring robust bidirectional data transfer between different voltage domains. The wide supply range accommodates various low-voltage logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments or applications with slower edge rates.

Part Context

This part belongs to the 74LVC245A-Q100 family of octal bus transceivers. It shares functional characteristics with other variants in the series but is distinguished by its specific SOIC-20 packaging and automotive-grade reliability certification. It serves as a bridge for high-speed data lines in complex electronic architectures.

Replacement Considerations

The 74LVCH245A-Q100 is a related variant within the same product family offering similar functionality.
