Overview
5962-9754701Q2A from Texas Instruments is a military-grade 4-bit magnitude comparator IC in LCCC-20 package, operating across –55°C to +125°C. It performs A>B, A For engineers reviewing the 5962-9754701Q2A datasheet, 5962-9754701Q2A pinout, 5962-9754701Q2A application, or 5962-9754701Q2A equivalent, this device serves as a QML-38534 Class V qualified logic comparator for deterministic digital decision-making in radiation-tolerant, extended-temperature control units and flight computer subsystems. The 5962-9754701Q2A implements TTL-compatible bipolar logic with LS (low-power Schottky) architecture, delivering propagation delays of 20 ns (typical) for A=B and 22 ns (typical) for A>B/A
Designed for military applications, it features SNPB (tin-lead) lead finish, non-RoHS compliance, and full screening per MIL-PRF-38534 Class V requirements including burn-in, temperature cycling, and hermeticity testing. Input thresholds align with standard TTL logic levels (VIH = 2.0 V min, VIL = 0.8 V max). LCCC (Leadless Ceramic Chip Carrier) package, FK outline, 20-terminal square body (8.89 mm × 8.89 mm), 1.27 mm pitch, ceramic substrate with solderable metallized terminations. Hermetically sealed, suitable for high-reliability, moisture-sensitive environments. Use Scenario: Comparing commanded vs. actual actuator position words in real-time servo control loops. IC Role / Device Role / Timing Role: Performs deterministic 4-bit magnitude comparison to trigger correction signals within fixed-cycle timing budgets. Use Value: Enables cycle-accurate decision latency (≤22 ns) critical for closed-loop stability in analog-digital hybrid flight control systems. Use Scenario: Detecting threshold crossings between target range data and seeker output in terminal guidance phase. IC Role / Device Role / Timing Role: Serves as hardwired comparator in safety-critical guidance logic, independent of software execution. Use Value: Provides fail-operational hardware-level comparison with no firmware dependency or interrupt latency. Use Scenario: Validating memory-mapped peripheral address ranges during secure boot and runtime access control. IC Role / Device Role / Timing Role: Implements fixed-function address window decoding in tamper-resistant crypto ASIC companion logic. Use Value: Delivers glitch-immune, side-channel-resistant address validation without microcontroller involvement. Use Scenario: Verifying telemetry packet header checksums against precomputed reference values before transmission. IC Role / Device Role / Timing Role: Executes parallel bit-wise comparison of 4-bit checksum segments in pipeline stages. Use Value: Reduces error detection latency by 4× versus serial CRC computation, improving real-time fault response. The following parts are listed as comparable options for similar 4-bit magnitude comparator applications. Compared with 5962-9754701Q2A, JM38510/31101B2A offers identical performance and reliability under JAN nomenclature, while SNJ54LS85FK provides functional equivalence at lower screening rigor-making the former a direct logistics alternative and the latter a risk-adjusted cost option. 5962-9754701Q2A is available at Aetrix Electronics and suitable for flight control systems, missile guidance electronics, secure crypto modules, and rad-hard telemetry subsystems requiring stable component supply across extended product lifecycles. Supply support for 5962-9754701Q2A includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs. Texas Instruments is a U.S.-based semiconductor company founded in 1930, specializing in analog, embedded processing, and high-reliability logic solutions for industrial, automotive, and defense markets. The 5962-9754701Q2A belongs to TI's military logic family derived from the classic 74LS85 architecture, engineered specifically for deterministic digital comparison in mission-critical avionics and space-qualified electronics. The 5962-9754701Q2A operates over –55°C to +125°C, meeting MIL-PRF-38534 Class V environmental requirements. This range is validated through temperature cycling and parametric testing across extremes, ensuring reliable functionality in jet engine bays, satellite payload compartments, and missile canisters where thermal stress is severe. The 5962-9754701Q2A maintains specified propagation delay and output drive strength throughout this full range. No, the 5962-9754701Q2A uses SNPB (tin-lead) lead finish and is explicitly marked "No" for RoHS compliance in TI's packaging documentation. It is intended for legacy military and aerospace systems requiring tin-lead solder compatibility and exempt from RoHS Directive restrictions under applicable defense procurement clauses. The 5962-9754701Q2A remains actively produced for these use cases. The 5962-9754701Q2A supports cascading via three dedicated inputs (IA>B, IA The 5962-9754701Q2A uses an LCCC (Leadless Ceramic Chip Carrier) package, designation FK, with 20 solderable metallized terminations arranged in a 8.89 mm × 8.89 mm square body and 1.27 mm pitch. It is hermetically sealed, non-RoHS, and qualified for high-reliability applications per MIL-PRF-38534. The 5962-9754701Q2A's LCCC construction provides superior thermal dissipation and moisture resistance compared to plastic DIP variants. The 5962-9754701Q2A is functionally identical to the SN74LS85 but built to military specifications: wider temperature range (–55°C to +125°C vs. 0°C to +70°C), QML-38534 Class V screening, SNPB terminations, and LCCC packaging. It cannot directly replace commercial SOIC or PDIP 74LS85s due to incompatible footprint and soldering requirements. However, the 5962-9754701Q2A delivers enhanced reliability where environmental robustness is mandatory.Technical Context

Selection Advice
JM38510/31101B2A
Identical LCCC-20 package, same QML-38534 Class V screening, but marked per JAN specification with different lot trace format
No functional difference; used interchangeably in DoD logistics channels where JAN nomenclature is mandated
Select JM38510/31101B2A when procurement documentation requires JAN-standard part numbering and trace reporting
SNJ54LS85FK
Same die and LCCC-20 package, but screened to older MIL-STD-883 Class B instead of QML-38534 Class V; lacks burn-in and some life test requirements
Suitable for non-safety-critical subsystems where full Class V reliability is not mandated
Choose SNJ54LS85FK only for cost-sensitive programs accepting reduced lifetime assurance and screening depth
