Overview
The UC161AJ is a high-reliability, military-grade comparator manufactured by Texas Instruments. It features four independent comparators within a single package, designed for operation in extreme environments. The device utilizes bipolar technology and is housed in a ceramic dual in-line package (CDIP-16). It supports a wide operating temperature range from -55°C to +125°C, ensuring stable performance under harsh conditions typical of aerospace and defense applications.
Feature Summary
- Contains four independent comparator circuits for multi-channel signal processing
- Constructed with bipolar technology for robust performance
- Housed in a hermetic ceramic dual in-line package for environmental protection
- Rated for extended industrial and military temperature ranges
Applications
- Aerospace and defense electronic systems
- Military-grade instrumentation and control circuits
- Harsh environment signal conditioning
- High-reliability voltage monitoring systems
Procurement Notes
Verify the manufacturer source carefully, as multiple vendors list this part. Confirm the specific suffix 'AJ' denotes the ceramic DIP package and military grade. Request official datasheets to validate electrical characteristics against your design requirements. Ensure compatibility with existing PCB footprints for CDIP-16 packages. Check for lead-free or RoHS compliance status if required by your project specifications.
Selection Notes
Select the UC161AJ when high reliability and radiation hardness are critical. It is suitable for designs requiring multiple comparators in a single package without compromising on temperature stability. Consider the ceramic package size constraints compared to plastic alternatives. Evaluate power supply requirements against the bipolar technology specifications. Ensure the input voltage ranges match the system signals being monitored.
Part Context
This component belongs to the family of high-performance linear comparators produced by Texas Instruments. It is distinct from logic families like the SN54LS161AJ counter, which shares similar alphanumeric characters but serves a different function. The UC series typically denotes specialized analog components designed for demanding operational environments.
Replacement Considerations
Direct substitutes may include other military-grade quad comparators from manufacturers like Analog Devices or Maxim Integrated. Verify pinout compatibility and electrical parameters such as offset voltage and propagation delay before substitution. Generic commercial-grade comparators are not suitable replacements due to temperature and reliability differences.
