Overview
The Texas Instruments 5962-9758501QRA is a military-grade SN54F240 octal buffer and driver featuring inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. The device utilizes a 20-pin Ceramic Dual In-Line Package (CDIP, J). Key electrical specifications include a quiescent current of 63 mA and a high-level output current capability of 12 mA.
Feature Summary
- Octal configuration providing eight independent inverting buffer/driver channels
- Three-state output control for bus-oriented applications
- Military qualification ensuring reliability in extreme environments
- Bipolar technology construction for high-speed signal processing
Applications
- Military communication systems requiring robust signal buffering
- High-reliability computing equipment operating in extreme temperatures
- Bus-oriented memory and interface circuits
- Industrial control systems demanding wide temperature stability
Procurement Notes
Verify the specific ordering suffix QRA to confirm the military grade and ceramic package variant. Ensure compatibility with existing board layouts for the 20-pin CDIP footprint. Confirm that the bipolar technology requirements align with system design constraints. Validate that the supply voltage and thermal specifications meet the operational environment standards before finalizing procurement decisions.
Selection Notes
Select this component when military-grade reliability and wide temperature operation are mandatory. The SN54 series designation indicates suitability for harsh environments compared to commercial variants. Consider the bipolar technology characteristics for speed and drive strength requirements. Ensure the three-state functionality matches the system's bus management architecture needs.
Part Context
This part belongs to the SN54F240 family of octal buffers and drivers manufactured by Texas Instruments. The SN54 series is distinguished by its military qualification and extended temperature range capabilities. It serves as a critical interface component in high-reliability digital systems where signal integrity and environmental resilience are paramount.
Replacement Considerations
Cross-reference with other SN54F240 variants or equivalent military-grade octal buffers. Verify pinout compatibility and electrical specifications such as supply voltage and output current. Ensure the replacement maintains the required three-state functionality and temperature rating.
