SN74LV273APWRG4

Flip Flops Overview

The SN74LV273APWRG4 is an octal D-type flip-flop from Texas Instruments, featuring a positive-edge clock trigger and an asynchronous clear input. It operates within a supply voltage range of 2 V to 5.5 V, supporting mixed-mode operation across all ports with latch-up performance exceeding 250 mA per JESD17 standards. The device utilizes a TSSOP-20 surface-mount package and supports a wide operating temperature range from -40°C to +125°C. Key electrical parameters include a propagation delay of 22.1 ns, high-level output current of -12 mA, and low-level output current of 12 mA.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Asynchronous clear function for immediate reset of all outputs regardless of clock state
• Mixed-mode voltage operation capability allowing inputs at different voltage levels
• High electrostatic discharge protection and robust latch-up performance

Flip Flops Applications

• Power substation control systems
• I/O modules in analog PLC and DCS applications
• Human-machine interface (HMI) circuits
• Flow meter signal processing
• Patient monitoring equipment

Flip Flops Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green status as per manufacturer documentation. Confirm the TSSOP-20 package dimensions match PCB footprint requirements. Check for automotive qualification if AEC-Q100 certification is required, noting that standard variants may differ from automotive-specific part numbers like those ending in AQ. Ensure lead times align with production schedules.

Flip Flops Selection Notes

Select this component when an octal storage element is needed with low-voltage compatibility down to 2 V. The LV series offers faster switching speeds compared to HC or HCT counterparts while maintaining CMOS input characteristics. Consider the TSSOP-20 package for space-constrained designs requiring surface-mount technology. Verify that the 22.1 ns propagation delay meets system timing constraints.

Flip Flops Part Context

This part belongs to the SN74LV273A family of octal D-type flip-flops. It is distinct from the SN74LV373A which includes tri-state outputs, and the SN74LVTH273A which features TTL-compatible inputs. The 'G4' suffix typically denotes environmental compliance and packaging variations within the broader SN74LV logic product line manufactured by Texas Instruments.

Flip Flops Replacement Considerations

Direct pin-to-pin replacements include SN74LV273ADWR and SN74LV273ADBRE4. For automotive applications, consider SN74LV273AQDGSRQ1. Verify that alternative packages such as SOIC or SSOP meet mechanical constraints before substitution.
