SN74LV273ADBRE4

Flip Flops Overview

The SN74LV273ADBRE4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the LV logic series. It features eight circuits with CMOS input and output types in a non-inverting configuration. The device operates within a supply voltage range of 2 V to 5.5 V and supports surface mount installation in a 20-SSOP package. 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. It functions across a temperature range of -40 C to +125 C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with integrated clear functionality
• Supports mixed-mode operation across all ports for flexible voltage interfacing
• High latch-up performance exceeding JESD 17 standards

Flip Flops Applications

• Power substation control systems
• I/O modules in analog PLC/DCS inputs
• Human-machine interface (HMI) devices
• Flowmeter applications
• Patient monitoring equipment

Flip Flops Procurement Notes

Verify the specific suffix E4 against official Texas Instruments documentation to confirm compliance with RoHS directives and environmental specifications. Ensure the SSOP-20 package dimensions align with PCB footprint requirements. Confirm that the operating temperature range meets system thermal constraints before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2 V and 5.5 V. The LV series offers suitable speed for general synchronous logic applications. Consider the 20-SSOP package for space-constrained surface mount designs. Verify that the 22.1 ns propagation delay satisfies timing requirements for the target clock frequencies.

Flip Flops Part Context

This part belongs to the SN74LV273A family of octal D-type flip-flops. The RE4 suffix typically indicates specific packaging or environmental compliance variations compared to standard versions like the SN74LV273ADBR. It shares functional similarities with other LV series components but is distinct in its pinout and package geometry.

Flip Flops Replacement Considerations

The SN74LV273ADBR is a confirmed substitute part number within the same product family. Both share identical logical functions and electrical characteristics. Verify package compatibility as both utilize the 20-SSOP form factor.
