SN54HC11J

Overview

The SN54HC11J is a military-grade triple 3-input positive-AND gate manufactured by Texas Instruments. It belongs to the HC (High-speed CMOS) logic family and operates within a supply voltage range of 2V to 6V. The device features three independent AND gates, each with three inputs, housed in a 14-pin ceramic dual in-line package (CDIP). Designed for high-speed applications, it offers low power consumption and wide operating temperature capabilities suitable for harsh environments.

Feature Summary

• Triple 3-input positive-AND logic function
• Military-grade reliability with extended temperature range
• CMOS technology for low power consumption

Applications

• Military avionics systems
• Spacecraft digital logic circuits
• Harsh environment industrial control

Procurement Notes

Verify the specific suffix 'J' indicates the ceramic DIP package and military grade. Confirm RoHS compliance status as military parts often differ from commercial standards. Ensure the supplier provides traceability documentation required for defense or aerospace procurement contracts.

Selection Notes

Select this component when military qualification and radiation hardness are required alongside standard HC logic performance. Compare against SN54HCT11J if TTL-compatible input levels are necessary instead of standard CMOS thresholds. Verify package availability and lead times for ceramic packages which may differ from plastic variants.

Part Context

This part is part of the SN54xx series, designated for military specifications including extended temperature ranges and stricter manufacturing controls compared to the commercial SN74xx series. The HC family provides speed comparable to LS TTL but with significantly lower power dissipation.
