74HC27P-E

Overview

The HD74HC27P-E is a CMOS logic integrated circuit belonging to the HC/UH series, manufactured by Renesas Electronics. It functions as a triple 3-input NOR gate housed in a 16-pin Dual In-line Package (PDIP). The device operates synchronously and is designed for general-purpose digital logic applications requiring standard voltage levels.

Feature Summary

• Triple 3-input NOR gate configuration
• CMOS technology with low power consumption
• Standard 5V drive capability

Applications

• General-purpose digital logic circuits
• Industrial control systems
• Consumer electronics logic interfaces

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation to confirm lead-free status and RoHS compliance. Ensure the PDIP-16 package matches the design footprint requirements. Confirm availability status as legacy support may be limited for older HC series components.

Selection Notes

Select this component when a triple 3-input NOR function is required in a through-hole DIP package. Compare propagation delay specifications against system timing constraints. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the widely adopted HC/UH logic family, known for compatibility with standard TTL logic levels while offering CMOS efficiency. The HD74HC27P-E represents a legacy product line originally developed by Hitachi before the formation of Renesas Electronics, maintaining high market penetration over decades.

Replacement Considerations

Compatible substitutes include other manufacturers' HD74HC27 equivalents or generic 74HC27 variants. Verify pinout compatibility and electrical characteristics such as input/output current ratings before substitution.
