74HCT27BQ,115

Overview

The Nexperia 74HCT27BQ,115 is a triple 3-input NOR gate integrated circuit belonging to the 74HCT logic family. It operates on a single power supply ranging from 4.5 V to 5.5 V and features TTL-compatible input levels. The device incorporates clamp diodes on its inputs, allowing for current limiting resistors when interfacing with voltages exceeding VCC. It provides high noise immunity and low power dissipation characteristics typical of CMOS technology.

Feature Summary

• Triple 3-input NOR logic function
• TTL-compatible input voltage levels
• Input clamp diodes for overvoltage protection
• High noise immunity and low power consumption

Applications

• Digital logic signal processing
• Interface circuits requiring TTL-to-CMOS translation
• General-purpose combinational logic design

Procurement Notes

Verify the specific ordering suffix matches the DHVQFN14 package configuration. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a triple 3-input NOR gate is required within a 5 V logic system. The HCT series ensures compatibility with TTL-driven signals while maintaining CMOS output drive capabilities. Consider the DHVQFN14 package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Part Context

This part is manufactured by Nexperia USA Inc. and falls under the 74HCT series of logic ICs. It utilizes the DHVQFN14 (SOT762-1) surface-mount package, which measures 2.5 x 3 mm with a body height of 0.85 mm. The device is designed for applications requiring robust performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes include other manufacturers' 74HCT27 devices in compatible packages. Verify pinout compatibility and electrical specifications before substitution.
