74HC27PW,118

Overview

The Nexperia 74HC27PW,118 is a triple 3-input NOR gate in the 74HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +125 °C and utilizes a TSSOP14 package.

Feature Summary

• Triple 3-input NOR logic function
• Wide supply voltage range from 2.0 V to 6.0 V
• CMOS low power dissipation and high noise immunity
• Input clamp diodes for overvoltage interfacing

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing systems
• General-purpose logic applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through official datasheets or environmental files before procurement. Check for any product change notifications that may affect pinout or electrical characteristics. Ensure the supplier source is authorized to guarantee authenticity and traceability.

Selection Notes

Select this component when a triple 3-input NOR gate is required in a surface-mount TSSOP14 package. It is suitable for designs operating between 2.0 V and 6.0 V with standard CMOS logic levels. Consider the 74HCT27 variant if TTL-compatible input levels are necessary instead of CMOS levels. Verify thermal derating requirements for total power dissipation based on the ambient temperature conditions.

Part Context

This part belongs to the Nexperia 74HC/HCT series of logic integrated circuits. The 74HC27 specifically implements three independent 3-input NOR gates within a single package. It is designed for general-purpose digital applications where low power consumption and high noise immunity are prioritized. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package.

Replacement Considerations

The 74HC27DB,118 serves as a direct replacement using the SO14 package. Other compatible parts include the 74HCT27PW,118 for TTL-level inputs and the 74HC27BQ,118 for DHVQFN14 packaging.
