SN74LV273ADBRG4

Flip Flops Overview

The SN74LV273ADBRG4 is an octal D-type flip-flop manufactured by Texas Instruments, featuring a positive-edge clock trigger and a master reset input. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode operation across all ports. The device provides non-inverting outputs with a maximum propagation delay of 6.2ns at 5V and 50pF load. It offers high output drive capability with 12mA source and sink currents, low static current of 20µA, and overvoltage tolerant inputs exceeding 250mA latch-up protection per JESD17 standards.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation on all ports for flexible system integration
• Features overvoltage tolerant inputs with robust latch-up performance
• Provides balanced push-pull outputs for reliable signal transmission

Flip Flops Applications

• Power substation control systems
• I/O modules in analog PLC/DCS applications
• Human-machine interface (HMI) designs
• Flowmeter data acquisition circuits
• Patient monitoring equipment interfaces

Flip Flops Procurement Notes

Verify the G4 suffix indicates compliance with RoHS3 specifications and REACH requirements. Confirm the package type matches the required SSOP-20 footprint for PCB layout. Ensure the operating temperature range aligns with the specific environmental conditions of the target application. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Flip Flops Selection Notes

Select this component when an octal storage element is required for parallel data handling in industrial or consumer electronics. It is suitable for applications needing mixed-voltage compatibility between 2V and 5.5V domains. Consider its speed and drive strength for bus interfacing tasks where moderate propagation delay is acceptable. Evaluate the 20-pin SSOP package constraints against available board space.

Flip Flops Part Context

This part belongs to the SN74LV273 family of octal D-type flip-flops from Texas Instruments. It is designed for general-purpose logic applications requiring eight-bit storage with a common clock and reset. The LV series technology ensures low power consumption while maintaining high-speed performance suitable for various digital system architectures.

Flip Flops Replacement Considerations

SN74LV273ADBR is the standard commercial version without the G4 suffix. SN74LV273ADBRE4 is an alternative variant with different environmental compliance markings.
