SN74LV273APWT

Flip Flops Overview

The SN74LV273APWT is an octal D-type flip-flop from Texas Instruments' LV logic family, housed in a TSSOP-20 package. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode port operation. The device features non-inverting CMOS outputs with a maximum propagation delay of 10.5 ns at 5 V. It includes a direct clear function and offers over-voltage tolerant inputs exceeding 5.5 V. The component is rated for industrial temperatures from -40°C to +125°C and provides latch-up performance greater than 250 mA per JESD 17 standards.

Flip Flops Feature Summary

• Supports mixed-mode voltage operation across all ports
• Features over-voltage tolerant inputs compatible with 5 V systems
• Enables partial power-down mode via Ioff functionality

Flip Flops Applications

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

Flip Flops Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified -40°C to +125°C operating range for reliable performance in industrial environments.

Flip Flops Selection Notes

Select this component for designs requiring wide voltage compatibility between 2 V and 5.5 V rails. It is suitable for applications needing high-speed data latching with low power consumption. Consider the TSSOP-20 footprint for space-constrained PCB layouts. Verify input voltage levels match the over-voltage tolerance specifications for system interfacing.

Flip Flops Part Context

This part belongs to the SN74LV273A series of octal D-type flip-flops. It shares functional similarities with other variants like SN74LV273ADWR but differs in package type. The LV series is designed for low-voltage applications while maintaining compatibility with legacy 5 V logic interfaces through robust input structures.

Flip Flops Replacement Considerations

SN74LV273ADWR serves as a pin-compatible alternative using a SOIC-20 package.
