SN74LV273APW

Flip Flops Overview

The SN74LV273APW is an octal D-type flip-flop from the Texas Instruments SN74LV273A series. It operates within a supply voltage range of 2 V to 5.5 V and features CMOS input and output types. The device provides eight non-inverting outputs with a propagation delay of 22.1 ns, high-level output current of -12 mA, and low-level output current of 12 mA. It is housed in a TSSOP-20 package and supports surface mount installation. The component functions across a temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation across all ports
• Includes latch-up performance exceeding 250 mA per JESD 17 standards
• Enables partial power-down mode via Ioff functionality

Flip Flops Applications

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

Flip Flops Procurement Notes

Verify the specific suffix against official documentation to confirm package type and environmental rating. Confirm availability status as some variants may be obsolete or subject to production change notifications. Ensure the selected part matches the required operating temperature range and voltage specifications for the target application environment.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with wide voltage compatibility is required. The LV series offers lower power consumption compared to standard logic families while maintaining sufficient drive capability for most digital interfaces. Consider the TSSOP-20 package constraints regarding board space and thermal management during layout design.

Flip Flops Part Context

This device belongs to the SN74LV273A family of octal D-type flip-flops designed for low-voltage applications. The family includes automotive-grade variants such as the SN74LV273AQDGSRQ1 which meet AEC-Q100 standards. The SN74LV273A series is engineered for high-speed data latching in industrial and consumer electronics requiring robust noise immunity.

Flip Flops Replacement Considerations

SN74LV273ADWR is a compatible alternative offering identical logical functionality in a SOIC-20 package.
