SN74LVC74AQPWRG4Q1

Flip Flops Overview

The SN74LVC74AQPWRG4Q1 is a dual positive-edge-triggered D-type flip-flop from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 2V to 3.6V and features a TSSOP-14 package. The device supports mixed-mode voltage operation and includes independent set and reset inputs. Key electrical parameters include a maximum propagation delay of 5.2ns at 3.3V with 50pF load, output drive currents of ±24mA, and a static current of 10µA. It functions reliably across an operating temperature range of -40°C to +125°C.

• Supports mixed-mode voltage operation across all ports
• Ioff circuitry enables partial power-down mode protection
• ESD protection exceeding JESD 22 standards

Flip Flops Applications

• Automotive electronic control units (ECUs)
• Programmable logic controllers (PLCs)
• Server power supply systems
• Set-top boxes and digital video recorders

Flip Flops Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status. Confirm the Q1 designation aligns with required AEC-Q100 automotive grade specifications. Ensure the TSSOP-14 package matches PCB footprint requirements. Validate that the 2V-3.6V operating range suits the target system voltage. Check datasheet revisions for any recent design changes.

Flip Flops Selection Notes

Select this component when dual D-type storage with set/reset functionality is required in automotive environments. It is suitable for designs needing mixed-voltage interface compatibility between 2V and 3.6V domains. Consider its 24mA output drive capability for moderate load driving. Verify that the 5.2ns propagation delay meets timing constraints. Ensure thermal performance fits the -40°C to +125°C application window.

Flip Flops Part Context

This part belongs to the SN74LVC74A-Q1 family of dual D-type flip-flops. It shares functional characteristics with other automotive-grade logic devices but is distinct in its LVC series voltage range and speed. The Q1 suffix denotes automotive qualification, while G4 indicates environmental compliance. It complements other TI automotive logic solutions like HC and AHCT series parts.

Flip Flops Replacement Considerations

SN74LVC74AQDRG4Q1 offers identical functionality in a SOIC-14 package. SN74LV74AQPWRG4Q1 provides similar features but with a wider 2V-5.5V supply range. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same AEC-Q100 automotive reliability standards.
