74AHC273PW,118

Overview

The Nexperia 74AHC273PW,118 is an octal D-type flip-flop with a positive-edge trigger and output enable function. It operates within a supply voltage range of 2.0 V to 5.5 V and features low static power consumption. The device utilizes TSSOP-20 surface-mount packaging and supports operation temperatures from -40 °C to +125 °C. Key electrical parameters include a propagation delay of 6 ns at 5 V, high-level output current of -8 mA, and low-level output current of 8 mA.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering for efficient data storage
• Integrated output enable control to manage bus states and reduce power consumption
• CMOS technology ensuring low static power dissipation across the operating voltage range
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 standards

Applications

• Parallel-to-serial data conversion circuits
• General-purpose memory registers in digital systems
• Bus-oriented logic designs requiring data latching
• Timing synchronization elements in microprocessor interfaces

Procurement Notes

Verify the complete part number including the suffix ,118 to ensure correct reel packaging configuration. Confirm RoHS compliance status through official Nexperia documentation prior to integration. Check for any recent Product Change Notifications (PCN) regarding package or assembly updates. Ensure design compatibility with the specified TSSOP-20 thermal and mechanical constraints.

Selection Notes

Select this component when an octal register with output enable is required for 2 V to 5.5 V systems. Compare against 74AHCT variants if TTL-compatible input levels are necessary instead of CMOS levels. Consider the TSSOP-20 package for space-constrained PCB layouts. Evaluate propagation delay specifications against system clock requirements to ensure timing margins are met.

Part Context

This component belongs to the Nexperia 74AHC series, which offers high-speed CMOS performance with wide supply voltage flexibility. It serves as a standard solution for general-purpose logic applications requiring reliable data storage and transfer capabilities in modern electronic designs.

Replacement Considerations

Direct substitutes include other manufacturers' 74AHC273 equivalents in TSSOP-20 packages. Verify pinout compatibility and electrical parameter alignment before substitution.
