SN74LV74APWRE4

Flip Flops Overview

The SN74LV74APWRE4 is a dual positive-edge-triggered D-type flip-flop from Texas Instruments, designed for operation within a 2V to 5.5V supply voltage range. It features set and reset functions with complementary outputs, packaged in a 14-TSSOP surface-mount case. The device supports mixed-mode voltage operation across all ports and includes Ioff circuitry to prevent destructive backflow currents during partial power-down conditions. It offers robust ESD protection exceeding JESD 22 standards and operates reliably within a temperature range of -40°C to 125°C.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation on all ports
• Includes Ioff circuitry for partial power-down applications
• Provides robust ESD protection performance

Flip Flops Applications

• Programmable Logic Controllers (PLC)
• DCS and PAC analog input modules
• AV receivers
• Server power supplies
• Set-top boxes, DVRs, and streaming extractors

Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates an environmental compliance variant or lead-free designation as per manufacturer documentation. Confirm the package type matches the required 14-TSSOP footprint and pinout. Ensure the operating temperature range aligns with system requirements. Cross-reference the datasheet revision history for any recent design changes. Validate that the component meets RoHS3 specifications for the target market.

Flip Flops Selection Notes

Select this component when dual D-type flip-flops are required for low-voltage logic systems. It is suitable for designs needing mixed-voltage interface capabilities between different logic families. The Ioff feature makes it ideal for systems requiring safe partial power-down states. Consider the 14-TSSOP package for space-constrained surface-mount applications. Verify compatibility with the intended clock frequencies and output drive requirements.

Flip Flops Part Context

This part belongs to the SN74LV74A series of dual D-type flip-flops. It is functionally equivalent to other variants in the LV family but may differ in packaging or environmental certifications. The 'E4' suffix typically denotes a specific manufacturing or compliance variation within the broader SN74LV74A product line. It shares core electrical characteristics with standard SN74LV74A devices while adhering to specific supply chain or regulatory requirements defined by Texas Instruments.

Flip Flops Replacement Considerations

SN74LV74APWR is a direct functional substitute within the same series. SN74LV74ARGYRG4 offers similar functionality in a VQFN-14 package. SN74LV74APWRG4 is another compatible variant with potential environmental differences.
