74LVCH16374ADGG-QJ

Overview

The Nexperia 74LVCH16374ADGG-QJ is a 16-bit D-type flip-flop with 3-state outputs, designed for automotive applications. It operates within a supply voltage range of 1.2 V to 3.6 V and complies with AEC-Q100 Grade 1 qualification. The device features Schmitt-trigger inputs for noise immunity and includes I_OFF circuitry to support partial power-down modes. Packaged in a TSSOP-48 surface-mount format, it ensures reliable data storage and transfer in mixed-voltage environments.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• I_OFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• 5 V tolerant inputs allow direct interfacing with 3.3 V and 5 V devices

Applications

• Automotive electronic control units (ECUs)
• Mixed-voltage data bus interfaces
• Partial power-down system architectures
• High-speed digital signal processing storage

Procurement Notes

Verify the specific suffix 'QJ' against the manufacturer's official datasheet to confirm AEC-Q100 Grade 1 compliance and temperature range specifications. Ensure the ordering part number matches the exact package variant and tape/reel configuration required for your assembly process. Cross-reference the 12NC code for accurate chemical content and RoHS status verification prior to procurement.

Selection Notes

Select this component when designing automotive systems requiring robust 16-bit latching with high noise immunity. The LVCH series is appropriate for applications needing wide supply voltage flexibility between 1.2 V and 3.6 V. Consider the TSSOP-48 package constraints for PCB layout. Verify that the 3-state output capability aligns with your bus architecture requirements.

Part Context

This device belongs to Nexperia's LVCH logic family, which combines low voltage CMOS performance with 5 V tolerance. The 74LVCH16374 variant specifically provides 16-bit storage capabilities. The '-QJ' suffix denotes automotive-grade qualification, distinguishing it from standard commercial variants. It serves as a critical interface element in modern vehicle electronics where voltage translation and data integrity are paramount.
