Overview
The Texas Instruments 5962-8869101RA is a radiation-hardened, high-performance 8-bit identity comparator belonging to the SN54ALS520 series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -55°C to +125°C. The device is housed in a 20-pin Ceramic Dual In-Line Package (CDIP) designed for surface-mount or through-hole installation. This component provides reliable digital logic comparison capabilities suitable for harsh environments.
Feature Summary
- Radiation-hardened design ensuring reliability in space and military applications
- High-speed 8-bit identity comparison functionality
- Extended temperature operation for extreme environmental conditions
Applications
- Spacecraft avionics systems
- Military communication equipment
- High-reliability industrial control systems
Procurement Notes
Verify the specific ordering suffix and package variant against official Texas Instruments documentation before procurement. Confirm radiation hardness assurance requirements match project specifications. Ensure compatibility with existing board layouts for the 20-pin CDIP footprint. Validate that the manufacturer's quality certifications meet defense or aerospace standards.
Selection Notes
Select this component when radiation tolerance and high-speed digital comparison are critical. The ALS technology offers a balance of speed and power consumption. Verify that the 20-pin CDIP package fits the mechanical constraints of the enclosure. Ensure the operating voltage aligns with the system's 5V logic levels.
Part Context
This part is part of Texas Instruments' radiation-hardened logic family, specifically the SN54 series. It serves as a robust alternative to commercial-grade comparators in environments where ionizing radiation could cause single-event upsets or latch-up. The 5962 prefix indicates it is a microelectronic device manufactured under strict quality controls.
Replacement Considerations
Direct replacements must maintain the 5962-8869101RA designation or equivalent SN54ALS520 variants with identical radiation hardening. Verify pinout compatibility for the 20-pin CDIP package. Ensure substitute parts meet the same MIL-STD or NASA radiation qualification standards.
