Overview
The Texas Instruments 5962-9754101QCA is a military-grade quad 2-input NAND gate from the SN54LS37 series. It operates on a 4.5-V to 5.5-V bipolar supply and features a 14-pin CDIP package. The device supports an operating temperature range of -55°C to +125°C. Key electrical parameters include a propagation delay of 18 ns at 5 V, with output currents of -29 mA (high) and 48 mA (low).
Feature Summary
- Military-grade reliability for harsh environments
- Quad configuration with independent 2-input NAND gates
- Bipolar TTL logic technology
- Wide industrial and military temperature capability
Applications
- Military avionics systems
- Spacecraft digital logic circuits
- Ruggedized communication equipment
- Defense ground station processing
Procurement Notes
Verify the QDA/QCA suffix indicates specific quality assurance levels required by MIL-PRF-38534 or similar standards. Confirm the package type matches the design footprint. Ensure the supplier provides traceability documentation for military procurement compliance.
Selection Notes
Select this component when high-speed bipolar NAND logic is required in extreme temperature conditions. Compare against standard commercial LS series parts if environmental ratings are less critical. Verify power dissipation limits within the 14-pin CDIP thermal constraints.
Part Context
This part belongs to the SN54xx series, designed for military applications. It replaces older commercial variants with enhanced durability. The 5962 prefix denotes a direct chip buy or military lot version.
Replacement Considerations
SN54LS37J is the commercial equivalent. SN54LS37FK is a plastic DIP alternative. Verify pin compatibility and voltage thresholds before substitution.
FAQ
What is the logic function of the 5962-9754101QCA?
It contains four independent 2-input NAND gates.
Does this part support 3-state outputs?
No, it provides standard active-high NAND outputs without tri-state control.
