NLV74HC273ADTR2G

Flip Flops Overview

The NLV74HC273ADTR2G is an octal D-type flip-flop manufactured by onsemi, belonging to the 74HC logic series. It features a positive-edge trigger mechanism and non-inverting outputs within a single element configuration. The device operates on a supply voltage range of 2V to 6V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a maximum propagation delay of 25ns at 6V with 50pF load, static current of 4µA, and output currents of 7.8mA for both high and low states. It is housed in a 20-TSSOP package (4.40mm wide) and functions across a temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements.
• Positive-edge triggering ensures data capture occurs specifically on the rising clock edge.
• Non-inverting output type maintains logical consistency between input and output states.
• Integrated reset functionality allows for synchronous or asynchronous clearing of stored data.

Flip Flops Applications

• Data storage and buffering in digital signal processing systems
• Shift register implementations for serial-to-parallel conversion
• State machine design in embedded control applications

Flip Flops Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm that the specific lot matches the original specifications, as end-of-life status may affect long-term availability and supply chain stability for production runs.

Flip Flops Selection Notes

Engineers replacing this part should consider the MC74HC273ADTR2G-Q as a recommended alternative from onsemi. Selection criteria must account for the transition from the legacy NLV prefix to standard commercial or automotive grades. Verify that the replacement package remains compatible with existing PCB footprints and that voltage tolerances align with the system's 2V to 6V operational requirements.

Flip Flops Part Context

The NLV74HC273ADTR2G belongs to the broader 74HC273 family of octal D-type flip-flops. It shares functional similarities with other variants like the MC74HC273ADTR2G but differs in specific manufacturing prefixes and potential qualification standards. Understanding its position within the 74HC series helps in identifying compatible logic families for interface design and signal integrity management.

Flip Flops Replacement Considerations

The MC74HC273ADTR2G-Q is explicitly recommended by the manufacturer as a substitute. Ensure pinout compatibility and verify that any automotive or industrial qualifications required for the new design are met by the replacement part number.
