Overview
The CLVC374AQDWRG4Q1 is an automotive-grade octal edge-triggered D-type flip-flop from Texas Instruments, belonging to the LVC logic series. It features eight non-inverting D-type flip-flops with 3-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 1.65 V to 3.6 V and supports CMOS and TTL input levels. Key electrical parameters include a propagation delay of 9.5 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It is qualified under AEC-Q100 standards for operation between -40°C and +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliable performance in vehicle environments.
- Octal configuration providing eight independent D-type flip-flops with shared clock and enable control.
- 3-state output capability allows direct connection to bus lines without additional interface hardware.
- Wide operating temperature range ensures stability across extreme automotive thermal conditions.
Applications
- Data storage registers in automotive infotainment systems
- I/O buffering for automotive microcontrollers
- Memory address latching in vehicle control units
- Signal synchronization in automotive communication buses
Procurement Notes
Verify AEC-Q100 certification status and specific grade requirements against target application specifications. Confirm package integrity and lead time availability through authorized distributors. Ensure compatibility with existing PCB footprint and reflow soldering profiles. Validate supply chain authenticity to prevent counterfeit components in automotive production lines.
Selection Notes
Select this component when automotive reliability and wide voltage operation are required. Compare propagation delay and drive strength against system timing constraints. Evaluate pin count and package size relative to board space limitations. Consider alternative LVC family members if different output configurations or input types are needed.
Part Context
This part belongs to the SN74LVC374A family of octal D-type flip-flops. It shares functional similarities with other automotive-qualified logic devices but offers specific LVC characteristics for low-voltage applications. The Q1 suffix indicates automotive qualification, distinguishing it from standard commercial variants while maintaining compatible pinouts and electrical behaviors.
Replacement Considerations
SN74LVC374ADW is a direct functional substitute within the same family. Verify that replacement parts maintain identical AEC-Q100 qualification and package dimensions for seamless integration into existing automotive designs without redesign requirements.
