SN74HC27D

Inverter Gates Overview

The SN74HC27D is a triple 3-input positive-NOR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 14-SOIC package. The device features low static current consumption and high noise immunity typical of CMOS technology. Electrical specifications include a propagation delay of 23 ns at 5 V, with output drive capabilities of 4 mA for both high and low states. It functions reliably across an industrial temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Integrates three independent 3-input NOR logic gates within a single integrated circuit.
• Provides high noise immunity and low power dissipation characteristic of HC CMOS technology.
• Supports direct interface with TTL logic families when operating at standard voltage levels.

Inverter Gates Applications

• Digital logic signal processing and combination circuits
• Microcontroller peripheral input conditioning
• General-purpose combinational logic design

Inverter Gates Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required RoHS compliance status for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before procurement.

Inverter Gates Selection Notes

Select this component for designs requiring multiple NOR functions in a compact surface-mount footprint. Verify that the 2 V to 6 V operating range aligns with the system power supply. Confirm that the 14-SOIC thermal characteristics meet the application's heat dissipation requirements under maximum load conditions.

Inverter Gates Part Context
