74HC27DB,118

Overview

The Nexperia 74HC27DB,118 is a triple 3-input NOR gate belonging to the HC 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 voltages exceeding VCC. It provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B and complies with JEDEC standards JESD8C and JESD7A. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is specified for ambient temperatures from -40 °C to +125 °C and utilizes an SO14 plastic small outline package.

Feature Summary

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

Applications

• General digital logic processing
• Signal gating and control circuits
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm RoHS compliance and REACH registration details prior to integration. Check for any recent product change notices or obsolescence announcements directly from the manufacturer. Ensure design-in compatibility with existing PCB footprints and thermal requirements.

Selection Notes

Select this component when a triple 3-input NOR gate is required in standard CMOS technology. It is suitable for applications needing operation across a wide voltage range up to 6.0 V. Consider the SO14 package dimensions for board space constraints. Verify that the input levels match the system's CMOS logic standards rather than TTL requirements.

Part Context

This part belongs to the 74HC series of logic ICs manufactured by Nexperia. The 'DB' designation indicates the SO14 package variant. The 74HC family is known for high-speed operation and low power consumption compared to older logic families. This specific device integrates three independent NOR gates into a single compact package.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 74HC27 triple 3-input NOR gates in SO14 packages. Verify pinout compatibility and electrical specifications before substitution.
