74HCT27PW,118

Overview

The Nexperia 74HCT27PW,118 is a triple 3-input NOR gate belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TSSOP-14 (SOT402-1) surface-mount packaging. The device features TTL-compatible input levels and includes internal clamp diodes on all inputs. Static characteristics specify low leakage current and defined output drive capabilities at recommended operating conditions.

Feature Summary

• Triple 3-input NOR logic function with single-ended outputs
• TTL-compatible input voltage levels for direct interfacing
• Input clamp diodes enable interface to voltages exceeding VCC using current limiting resistors
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 standards

Applications

• Digital logic circuit design requiring NOR functionality
• Signal processing systems utilizing TTL-level interfaces
• General-purpose logic applications in industrial control environments

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range specifications. Ensure compatibility with system voltage requirements and thermal management constraints before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. The TSSOP-14 package is suitable for space-constrained surface-mount designs. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature range.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices manufactured by Nexperia. The series provides performance comparable to standard TTL logic while maintaining lower power consumption typical of CMOS technology. The PW suffix indicates the specific thin shrink small outline plastic package variant.

Replacement Considerations

Cross-reference with other manufacturers' 74HCT27 equivalents to ensure pinout and electrical parameter compatibility. Verify that alternative sources meet the same JEDEC compliance and ESD protection standards.
