SN74HC27DBR

Inverter Gates Overview

The SN74HC27DBR is a triple 3-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC (High-speed CMOS) logic family and operates within a supply voltage range of 2 V to 6 V. The device features three independent NOR gates, each with three inputs and one output. Key electrical characteristics include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. Propagation delay is specified at 15 ns when operating at 6 V with a 50 pF load. The component supports surface-mount installation in a 14-SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Integrates three independent 3-input positive-NOR logic gates within a single integrated circuit.
• Utilizes High-speed CMOS technology to ensure low static power consumption and compatibility with standard CMOS outputs.
• Supports wide supply voltage operation ranging from 2 V to 6 V for flexible system integration.

Inverter Gates Applications

• Digital logic circuits requiring multiple NOR gate functions
• Signal processing systems utilizing CMOS logic families
• Industrial control equipment operating within extended temperature ranges

Inverter Gates Procurement Notes

Verify the specific suffix 'DBR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure that the selected variant matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement decisions.

Inverter Gates Selection Notes

Select this component when designing circuits that require multiple independent NOR operations within a compact surface-mount footprint. Consider the 2 V to 6 V supply range and propagation delay characteristics relative to the system clock speed. Verify that the 14-SOIC package dimensions align with the printed circuit board layout constraints and thermal management requirements.

Inverter Gates Part Context

This part is a member of the Texas Instruments SN74HC series, which provides high-speed CMOS logic functionality. The SN74HC27 specifically implements triple 3-input NOR gates. It is designed for general-purpose digital applications where low power consumption and wide voltage operation are prioritized over the higher drive capabilities found in other logic families.

Inverter Gates Replacement Considerations
