74HCT273PW,118

Overview

The Nexperia 74HCT273PW,118 is an octal D-type edge-triggered flip-flop housed in a 20-pin TSSOP package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device features eight positive-edge triggered D-type flip-flops with a common clock and master reset input. Key electrical parameters include a maximum propagation delay of 9 ns, a maximum power supply current of 8 uA, and an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggering mechanism synchronized by a common clock input for all channels
• Master reset functionality that forces outputs low independently of clock and data states
• Compliance with TTL logic levels ensuring compatibility with standard digital systems

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Timing and synchronization logic modules
• Buffering interfaces between different logic domains

Procurement Notes

Verify the complete part number including the suffix ,118 to ensure correct packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet revision history to validate pinout consistency and electrical characteristics against current production standards.

Selection Notes

Select this component when an octal storage solution compatible with HCT logic families is required. Ensure the system supply voltage remains within the specified 4.5 V to 5.5 V window. Consider the TSSOP-20 footprint dimensions during PCB layout planning to accommodate thermal and spacing requirements.

Part Context

This component belongs to the 74HCT series of high-speed CMOS logic devices manufactured by Nexperia. It serves as a fundamental building block for sequential logic designs requiring multiple bits of storage. The device integrates standard industrial-grade performance metrics suitable for commercial and industrial environments.

Replacement Considerations

The SN74HCT273PW from Texas Instruments is a confirmed functional substitute offering identical logical operations and pin configurations.
