SN74LV74AQPWRG4Q1

Flip Flops Overview

The SN74LV74AQPWRG4Q1 is a dual D-type flip-flop from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates on a supply voltage range of 2V to 5.5V and features Ioff support for partial power-down modes. The device is housed in a 14-pin TSSOP package and supports mixed-mode voltage operation across all ports. Key electrical parameters include a maximum propagation delay of 8.5ns at 5V and typical output bounce characteristics of less than 0.8V for VOLP and greater than 2.3V for VOHV at 3.3V.

Flip Flops Feature Summary

• Supports partial power-down operation via Ioff circuitry to prevent destructive backflow currents
• Enables mixed-mode voltage operation allowing 5V inputs with 3.3V or lower VCC supplies
• Provides robust ESD protection exceeding JESD 22 standards for human model and charged device model

Flip Flops Applications

• Programmable logic controllers (PLC)
• DCS and PAC analog input modules
• AV receivers
• Server power supply units (PSU)
• Set-top boxes, DVRs, and streaming media extractors

Flip Flops Procurement Notes

Verify the specific suffix G4Q1 indicates compliance with RoHS directives and automotive reliability standards. Confirm that the TSSOP-14 package matches the target PCB footprint requirements. Ensure the component meets the required temperature grade for the intended operational environment. Cross-reference the datasheet revision history for any recent design changes affecting pinout or electrical characteristics before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring dual edge-triggered storage elements with mixed-voltage compatibility. It is suitable for interfaces between 5V legacy logic and modern low-voltage microcontrollers. Consider the 8.5ns propagation delay for timing-critical paths. Verify that the Ioff feature aligns with system power management strategies involving partial shutdown states.

Flip Flops Part Context

This part belongs to the SN74LV74A-Q1 family of dual D-type flip-flops. It shares functional similarities with other automotive-grade logic devices but is distinct in its LV series voltage range and specific Ioff implementation. The Q1 suffix denotes automotive qualification, differentiating it from standard commercial variants like the SN74LV74A.
