SN74LV373AIPWRG4Q1

Latches Overview

The SN74LV373AIPWRG4Q1 is an octal transparent D-type latch with 3-state outputs, designed for automotive applications. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode voltage operation across all ports. The device features low output impedance and is qualified under AEC-Q100 standards. It ensures reliable performance in harsh environments with specified operating temperature ranges and robust latch-up protection characteristics compliant with JESD 78 standards.

Latches Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Supports mixed-mode voltage operation on all ports
• Provides local power-down protection via Ioff support
• Features robust latch-up protection exceeding 250mA

Latches Applications

• Automotive electronic control units
• In-vehicle network interfaces
• Display driver circuits
• Memory address/data latching systems

Latches Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance as per Texas Instruments documentation. Confirm the IPWR package variant matches the required TSSOP-20 footprint for PCB layout integration. Ensure the Q1 designation aligns with the target automotive reliability requirements before finalizing procurement orders.

Latches Selection Notes

Select this component when automotive-grade reliability is mandatory alongside high-speed data latching capabilities. The LV series offers lower power consumption compared to standard TTL equivalents. Verify that the 2V to 5.5V input compatibility matches the system's logic levels. Consider the TSSOP-20 package constraints for thermal management and board space availability.

Latches Part Context

This part belongs to the SN74LV373A family of octal latches. The 'IPWR' denotes the surface-mount TSSOP-20 package type. The 'G4' suffix typically signifies environmental enhancements such as lead-free manufacturing. The 'Q1' suffix specifically identifies it as an automotive-qualified product intended for use in vehicles.

Latches Replacement Considerations

Direct substitutes include other AEC-Q100 qualified octal latches from Texas Instruments. Cross-reference pinouts and electrical specifications carefully. Non-automotive grades like SN74LV373APWR lack the required qualification for automotive deployment.
