74LVCH16245ADGV-QJ

Overview

The Nexperia 74LVCH16245ADGV-QJ is a 16-bit bus transceiver with direction pin, 5 V tolerant, and 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for slow signal tolerance and IOFF circuitry for partial power-down protection. It complies with AEC-Q100 Grade 1 standards for automotive applications.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs up to 5.5 V
• IOFF circuitry prevents damaging backflow current during partial power-down
• Active bus hold on all data inputs eliminates need for external pull-up resistors

Applications

• Mixed 3.3 V and 5 V environments
• Partial power down applications
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary AEC-Q100 Grade 1 qualification requirements for your target application. Ensure compatibility with the specified operating temperature range and supply voltage conditions before finalizing procurement decisions.

Selection Notes

Select this component when a 16-bit bidirectional level translator is required for automotive or industrial environments. It is suitable for translating between different voltage domains while maintaining high noise immunity. Consider the TVSOP48 package dimensions if space constraints are a primary design factor.

Part Context

This part belongs to the 74LVC/LVCH16245A-Q100 family of 16-bit bus transceivers. It shares functional similarities with other members of the series but is distinguished by its specific LVCH logic characteristics and TVSOP48 packaging. The 'QJ' suffix indicates the specific automotive-grade qualification and package type.

Replacement Considerations

The 74LVC16245ADGV-Q100 serves as a direct functional replacement within the same family, differing primarily in logic family specifications.
