Overview
The SN54S03J is a quadruple 2-input positive-NAND gate featuring open-collector outputs, manufactured by Texas Instruments. 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 belongs to the S series logic family. Key electrical specifications include a maximum output low current of 0.02 A and a load capacitance of 15 pF.
Feature Summary
- Quadruple 2-input NAND logic functionality
- Open-collector output configuration for wired-OR applications
- Military-grade wide operating temperature range
Applications
- Military aerospace systems
- High-reliability industrial control
- Wired-logic bus structures
Procurement Notes
Verify component authenticity through authorized channels due to military grade status. Confirm package integrity as ceramic DIPs require careful handling. Check datasheet revisions for specific testing requirements. Ensure environmental compliance documentation matches project specifications. Validate supplier authorization for SN54 series components.
Selection Notes
Select this part when open-collector NAND logic with high drive capability is required. Suitable for interfacing with different voltage levels via pull-up resistors. Consider thermal management for 125°C operation. Verify pin compatibility if replacing older SN54 variants. Evaluate load capacitance limits for signal integrity.
Part Context
Part of the SN54S series offering Schottky-clamped performance. Provides faster switching than standard TTL while maintaining compatible logic levels. Ceramic packaging ensures reliability in harsh environments. Commonly used in defense and space applications requiring extended temperature tolerance.
Replacement Considerations
SN54LS03J offers lower power consumption but slower speed. SN54S03N provides plastic package alternative. SN5403J is standard TTL equivalent with different drive characteristics. Verify pinout and electrical parameters before substitution.
