SN54LS30J

Overview

The SN54LS30J is a military-grade TTL logic component featuring an 8-input NAND gate within the LS series. It utilizes a 14-pin ceramic dual in-line package (CDIP) with glass-sealed construction for environmental durability. The device operates across an extended temperature range of -55°C to 125°C and requires a supply voltage between 4.5V and 5.5V. Key electrical characteristics include a maximum propagation delay of 100 ns, a load capacitance of 50 pF, and a maximum supply current of 0.51 mA.

Feature Summary

• Military-grade reliability with extended temperature tolerance
• High-noise immunity inherent to Low-power Schottky technology
• Hermetically sealed ceramic packaging for harsh environments

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm exact pinout and performance specifications. Ensure the supplier provides traceability certificates appropriate for military-grade components. Confirm that the CDIP package matches the required footprint and sealing standards for the intended application environment.

Selection Notes

Select this component when designing systems requiring high noise immunity and low power consumption under extreme thermal conditions. The LS family offers a balance of speed and power suitable for complex logic operations. Verify compatibility with existing 5V logic levels and ensure the 8-input configuration meets the circuit design requirements without excessive fan-out limitations.

Part Context

This part belongs to the SN54xx series, designated for military specification compliance. Unlike commercial SN74xx variants, it supports wider temperature ranges and stricter manufacturing controls. The LS designation indicates Low-power Schottky technology, providing improved power-delay product compared to standard TTL families while maintaining robust signal integrity.
