SN74LV273ADBR

Flip Flops Overview

The SN74LV273ADBR is an octal D-type flip-flop from Texas Instruments' LV logic series, housed in a 20-SSOP package. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode port voltages. The device features non-inverting outputs with push-pull drive capabilities, providing 12 mA high-level and low-level output currents. It exhibits a maximum propagation delay of 6.2 ns at 5 V with 50 pF load and functions reliably across an operating temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Octal configuration with eight independent D-type flip-flops
• Supports mixed-mode operation for mixed-voltage interfaces
• High noise immunity with over 250mA latch-up performance per JESD17 standard

Flip Flops Applications

• Power substation control systems
• I/O modules in analog PLC/DCS inputs
• Human-machine interface (HMI) designs
• Flow metering instrumentation
• Patient monitoring equipment

Flip Flops Procurement Notes

Verify the specific ordering suffix 'E4' against official datasheets to confirm lead-free status and environmental compliance details. Ensure the SSOP-20 package dimensions match the target PCB footprint requirements. Confirm that the 2V to 5.5V operating range aligns with the system's power supply architecture before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal storage solution is required for low-voltage digital logic interfacing. The wide supply voltage range allows compatibility with both 3.3V and 5V systems. Consider the 6.2 ns propagation delay for timing-critical applications. The industrial temperature range makes it suitable for demanding environments where standard commercial grade parts may fail.

Flip Flops Part Context

This part belongs to the SN74LV273A family of octal D-type flip-flops. It serves as a parallel-to-serial or data storage element in digital circuits. The LV series is designed for low-power applications while maintaining high-speed performance. It is distinct from the LVTH series which uses TTL-compatible inputs and different voltage ranges.

Flip Flops Replacement Considerations

SN74LV273ADBRG4 is a verified equivalent variant within the same product family.
