Overview
The SN54LS03J is a military-grade quadruple 2-input positive-NAND gate featuring open-collector outputs. It operates within an extended temperature range of -55°C to 125°C and utilizes a 14-pin ceramic dual in-line package (CDIP). The device supports a maximum output load current of 24 mA and has a specified load capacitance of 15 pF.
Feature Summary
- Military-grade reliability with wide operating temperature range
- Open-collector outputs for wired-logic applications
- Quadruple 2-input NAND logic functionality
Applications
- Military aerospace systems
- High-reliability industrial control
- Wired-OR logic bus configurations
Procurement Notes
Verify the specific datasheet revision and manufacturer lot codes upon procurement. Confirm that the ceramic package integrity meets military specifications. Ensure compatibility with existing circuit designs regarding open-collector pull-up requirements and voltage levels before finalizing orders.
Selection Notes
Select this component when military-grade environmental tolerance and high noise immunity are required. The open-collector architecture allows flexible voltage level shifting. Verify that the system design accommodates the necessary external pull-up resistors associated with open-collector outputs.
Part Context
This part belongs to the Texas Instruments SN54LS series, designed for military applications. It provides standard NAND logic functions in a hermetically sealed ceramic package. The series ensures performance stability under extreme thermal conditions compared to commercial variants.
Replacement Considerations
SN54S03J: Faster switching speed but higher power consumption. SN54LS03K: Plastic package variant with lower environmental sealing.
