CD74HCT27E

Inverter Gates Overview

The CD74HCT27E is a triple 3-input NOR gate integrated circuit manufactured by Harris Corporation. It utilizes silicon gate CMOS technology to achieve operating speeds comparable to LSTTL gates while maintaining low power consumption. The device operates within a supply voltage range of 2V to 6V and features three-state outputs. It is housed in a 14-pin Dual In-Line Package (DIP) with a standard 0.300-inch width. The component supports an operating temperature range from -55°C to 125°C, ensuring reliability across industrial environments.

Inverter Gates Feature Summary

Inverter Gates Procurement Notes

Verify the specific manufacturer lot and RoHS compliance status prior to procurement, as the component may be marked as obsolete or non-compliant depending on the production batch. Confirm that the 14-DIP package dimensions match the target PCB footprint. Ensure that the supply voltage requirements align with the system design, as the device supports a wide operating range. Check for any specific handling precautions related to static-sensitive CMOS devices during installation.

Inverter Gates Selection Notes

Select this component when a triple 3-input NOR gate is required in a DIP package. It is suitable for designs needing LSTTL-compatible speeds with lower power dissipation. Consider the 2V to 6V supply range compatibility with existing logic levels. Verify that the 125°C maximum operating temperature meets the environmental constraints of the application. Ensure the 14-pin form factor fits the available board space.

Inverter Gates Part Context

The CD74HCT27E belongs to the 74HCT series of logic integrated circuits produced by Harris Corporation. This series bridges the performance gap between standard CMOS and Low-power Schottky TTL technologies. The device is part of a broader family of logic gates designed for general-purpose digital applications. Harris Corporation has since been acquired, and these components are often distributed through specialized semiconductor suppliers.

Inverter Gates Replacement Considerations

Compatible substitutes include the CD74HC27E for HC-series compatibility and generic 74HCT27 equivalents from other manufacturers. Verify pinout compatibility and electrical specifications before substitution.
