Overview
The SN54LS86AJ is a military-grade quadruple 2-input exclusive-OR gate belonging to the Texas Instruments SN54LS series. It utilizes Low-power Schottky (LS) bipolar technology to achieve high speed with reduced power consumption. The device features push-pull outputs and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 14-pin ceramic dual in-line package (CDIP) designed for reliability in harsh environments, supporting an extended operating temperature range from -55°C to 125°C.
Feature Summary
- Military-grade construction utilizing hermetic ceramic packaging for environmental resilience
- Low-power Schottky logic technology providing optimized speed-to-power performance
- Quadruple 2-input exclusive-OR functionality with push-pull output stages
Applications
- High-reliability digital logic circuits requiring XOR operations
- Parity checkers and error detection systems in aerospace applications
- Adder circuits in military-grade computing hardware
Procurement Notes
Verify the specific suffix 'AJ' corresponds to the authorized ceramic DIP package and military temperature rating. Confirm RoHS status as legacy military parts may not comply with current consumer restrictions. Ensure compatibility with existing CDIP footprints and soldering profiles suitable for ceramic packages during integration.
Selection Notes
Select this component when military qualification and hermetic sealing are mandatory requirements. The LS series offers a balance between speed and power dissipation compared to standard TTL. Consider the SN74LS86 for commercial applications where ceramic packaging and extended temperature ranges are unnecessary.
Part Context
This part belongs to the SN54xx family, designated for military specifications including strict screening and radiation hardness considerations. The 'LS' indicates Low-power Schottky technology, while '86' identifies the XOR gate function. The 'A' typically denotes the ceramic package variant, and 'J' specifies the dual in-line configuration.
Replacement Considerations
The SN54LS86 is a direct functional equivalent. For commercial use, the SN74LS86 provides identical logic but lacks military certification. Verify pinout compatibility before substitution.
