54S10FM

Overview

The 54S10FM is a Schottky TTL NAND gate manufactured by National Semiconductor. It features three independent functions, each with three inputs. The device utilizes a ceramic flatpack package with 14 pins. It operates within a temperature range of -55 °C to 125 °C and typically requires a 5 V power supply. The propagation delay is specified at 8 ns under nominal supply conditions.

Feature Summary

• Provides three independent 3-input NAND logic functions
• Utilizes Schottky TTL technology for high-speed switching
• Constructed in a hermetically sealed ceramic flatpack housing

Applications

• Military aerospace digital systems
• High-reliability industrial control circuits
• Harsh environment computing hardware

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm that the specific unit matches the original NS specifications rather than modern TI equivalents. Ensure the ceramic flatpack package integrity is intact upon receipt. Validate the part number suffix against official datasheets to confirm pinout compatibility.

Selection Notes

Select this component when military-grade reliability and wide temperature operation are required. The Schottky technology offers faster performance compared to standard LS series devices. The ceramic flatpack package provides superior environmental sealing for demanding applications. Verify voltage levels match the 5 V TTL requirement before integration into the design.

Part Context

This component belongs to the 54-series military grade logic family. It represents an evolution of earlier TTL designs with improved speed characteristics. The ceramic construction distinguishes it from plastic packaged commercial variants. It serves critical roles in systems requiring long-term stability and radiation hardness.
