SN54HC00J

Overview

The SN54HC00J is a quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It belongs to the HC (High-speed CMOS) logic family and features push-pull outputs. The device operates within a supply voltage range of 2V to 6V, with a maximum data rate of 28 Mbps. It supports an operating temperature range from -55°C to 125°C. The component is available in CDIP-14 and CFP-14 package groups.

Feature Summary

• Provides four independent 2-input NAND logic functions within a single integrated circuit.
• Utilizes high-speed CMOS technology for efficient power consumption and fast switching speeds.
• Features standard CMOS input types compatible with various logic families.
• Designed for robust performance across extended industrial and military temperature ranges.

Applications

• Digital signal processing circuits requiring basic logical operations
• Military and aerospace avionics systems demanding radiation-hardened or high-reliability components
• Industrial control systems operating in extreme environmental conditions

Procurement Notes

Verify the specific package variant (CDIP or CFP) required for your design, as both are listed under this part number series. Confirm that the HC logic family characteristics align with your system's voltage and speed requirements. Ensure compatibility with existing PCB footprints for ceramic dual in-line packages. Check for any specific ordering suffixes that might denote testing levels or screening standards.

Selection Notes

Select this component when multiple independent NAND gates are needed in a space-constrained environment. The HC family offers a balance between speed and power dissipation suitable for general-purpose digital logic. Consider the wide operating temperature range if the application involves harsh environments. Verify that the 2V to 6V supply range matches the system's power distribution network.

Part Context

This component is part of the broader SN54xx series, which typically denotes military-grade or high-reliability specifications compared to commercial SN74xx counterparts. The HC suffix indicates High-speed CMOS technology, distinguishing it from older TTL or lower-speed HC/UH variants. It serves as a fundamental building block for complex digital logic designs.

Replacement Considerations

Direct replacements may include other SN54HC00 variants with different packaging options such as SN54HC00FK or SN54HC00W, provided the pinout remains compatible. Cross-reference with SN54LS00J for TTL-compatible designs, noting significant differences in voltage and current characteristics. Always verify electrical parameters against the specific datasheet revision before substitution.
