Overview
The SN5403J is a quadruple 2-input positive-NAND gate manufactured by Rochester Electronics. It features open-collector outputs, allowing for wired-AND logic configurations and flexible voltage level interfacing. The device is characterized for operation over the full military temperature range of -55°C to 125°C. It belongs to the standard TTL logic family, providing reliable performance in harsh environments where extended thermal stability is required.
Feature Summary
- Contains four independent 2-input NAND gates within a single package
- Utilizes open-collector output structure for versatile logic interfacing
- Qualified for full military temperature range operation from -55°C to 125°C
Applications
- Military aerospace systems requiring extended temperature tolerance
- Industrial control logic with open-collector bus requirements
- Test and measurement equipment operating in extreme environments
Procurement Notes
Verify the specific manufacturer lot and date code upon receipt, as Rochester Electronics sources components from various qualified suppliers. Confirm that the packaging meets MIL-PRF-38535 Class Q or equivalent standards if required for your application. Ensure compatibility with your system's voltage levels, as open-collector outputs require external pull-up resistors to function correctly.
Selection Notes
Select this component when military-grade temperature ratings are mandatory and open-collector NAND functionality is needed. Compare against SN5403 variants from original manufacturers to ensure pinout and electrical characteristics match your design constraints. Consider the power dissipation limits and load capacitance requirements associated with open-collector drivers in your circuit analysis.
Part Context
This part is part of the SN54xx series of standard logic devices, widely used in legacy and high-reliability digital circuits. The 'J' suffix typically denotes a ceramic flatpack package, suitable for hermetic sealing in critical applications. It serves as a fundamental building block for complex logic functions in defense and space electronics.
Replacement Considerations
Direct replacements include SN5403J from Texas Instruments or other authorized foundries producing the same SN5403 specification. Verify that any substitute maintains the open-collector output type and military temperature range. Cross-reference with SN54LS03 only if speed and power consumption differences are acceptable.
