Product details
Overview
5962-8869101RA from Texas Instruments is a military-grade 8-bit identity comparator IC performing exact binary word equality detection between two parallel 8-bit inputs (P₀–P₇ and Q₀–Q₇), with totem-pole P = Q output, 4.5 V to 5.5 V supply operation, and full –55°C to +125°C temperature range. It enables precise data validation in avionics bus arbitration and secure cryptographic key comparison circuits.
For engineers reviewing the 5962-8869101RA datasheet, 5962-8869101RA pinout, 5962-8869101RA application, or 5962-8869101RA equivalent, this device delivers deterministic P = Q assertion within 3 ns minimum / 25 ns maximum propagation delay (tPHL) under military temperature extremes, supports direct interface to TTL/ALS logic families, and requires no external pullups due to its internally terminated totem-pole output stage.
Technical Context
The 5962-8869101RA implements a combinatorial equality function using advanced bipolar ALS (Advanced Low-Power Schottky) process technology. Its core logic compares all eight bit pairs simultaneously via cascaded NAND/NOR gates, with enable input G controlling output assertion state.
Unlike open-collector variants (e.g., SN74ALS518), the 5962-8869101RA uses a totem-pole output configuration delivering both sourcing and sinking capability (IOH = –2.6 mA, IOL = 24 mA), eliminating need for external pullup resistors while maintaining compatibility with standard 5 V TTL load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit parallel identity comparator with active-high P = Q output |
| Supply Voltage | 4.5 V to 5.5 V - operates across full military voltage tolerance band without derating |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class B for defense/aerospace deployment |
| Propagation Delay | tPHL = 5–23 ns (G → P = Q) - ensures sub-25 ns worst-case decision latency in real-time control loops |
| Output Type | Totem-pole - drives standard TTL loads directly; no external pullup required |
| Input Compatibility | Q inputs lack internal 20-kΩ pullups - requires externally driven or actively terminated Q-bus signals |
| Package | Ceramic Dual-In-Line Package (CDIP), J-body, 20-pin - hermetically sealed for high-reliability environments |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP-J), 20-pin, 300-mil width, hermetic ceramic construction with glass-sealed leads. Designed for high-reliability military, aerospace, and downhole applications requiring long-term stability under thermal cycling and humidity exposure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Enable) | Active-low global enable - output P = Q is forced low when G = H; comparator disabled |
| 2–9 | P₀–P₇ | First 8-bit operand input - direct connection to data bus or register output |
| 10 | GND | Signal ground reference - must be low-impedance connection to system ground plane |
| 11–18 | Q₀–Q₇ | Second 8-bit operand input - no internal pullups; requires active drive or termination |
| 19 | P = Q | Active-high totem-pole output - asserts high only when all eight P/Q bit pairs match exactly |
| 20 | VCC | +5 V power supply - bypass capacitor (0.1 µF) required adjacent to pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-38535 Class B qualification | Meets rigorous screening, burn-in, and lot acceptance test requirements for space- and defense-critical systems |
| Hermetic CDIP-J package | Zero moisture ingress; certified for 100% humidity and thermal shock per MIL-STD-883 Method 1010 |
| No Q-input pullups | Eliminates input leakage uncertainty in high-impedance or analog-switched data paths |
| 24 mA sink capability | Directly drives LED indicators, optocouplers, or TTL fan-out without buffer stages |
| Sub-25 ns worst-case tPHL | Enables use in 40 MHz+ synchronous bus monitoring and fault-detection timing windows |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit identity comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ALS520J | Identical electrical specs, same CDIP-J package, same MIL-PRF-38535 Class B qualification; differs only in TI's internal part numbering convention and marking format | No functional difference - interchangeable in all military/aerospace designs requiring 5962-8869101RA | Select SNJ54ALS520J if procurement documentation requires TI's legacy military nomenclature |
| 5962-88691012A | Same functionality and temperature range, but packaged in 20-pin ceramic LCCC (FK) instead of CDIP (J); different footprint and soldering profile | Used where board space constraints favor surface-mount LCCC over through-hole CDIP; requires PCB redesign | Choose 5962-88691012A only when migrating to surface-mount assembly or upgrading thermal performance via LCCC's lower thermal resistance |
Compared with SNJ54ALS520J, 5962-8869101RA offers identical performance and qualification but distinct traceability labeling per DoD standards; versus 5962-88691012A, it provides proven through-hole reliability and simplified rework in legacy avionics repair workflows without requiring SMT infrastructure.

FAQ
What is the operating temperature range of the 5962-8869101RA?
The 5962-8869101RA is characterized for continuous operation from –55°C to +125°C, fully compliant with MIL-PRF-38535 Class B environmental testing requirements. This range enables deployment in jet engine bays, satellite payload compartments, and downhole drilling equipment where ambient temperatures exceed commercial limits. The 5962-8869101RA maintains specified propagation delay and output drive strength across this entire span without derating.
Does the 5962-8869101RA have internal pullup resistors on its Q inputs?
No, the 5962-8869101RA does not include internal 20-kΩ pullup resistors on Q inputs - unlike SN74ALS518 or SN74ALS520. Its Q₀–Q₇ pins require externally driven signals or active termination. This design eliminates input leakage uncertainty in analog-switched or high-impedance data paths, making the 5962-8869101RA suitable for precision comparator applications where input bias current must be minimized.
What package type is used for the 5962-8869101RA?
The 5962-8869101RA uses a 20-pin Ceramic Dual-In-Line Package (CDIP-J) with 300-mil body width and hermetic ceramic construction. This package provides zero moisture ingress, superior thermal stability, and mechanical robustness for high-reliability military and aerospace applications. The 5962-8869101RA's CDIP-J footprint matches legacy MIL-STD-1835 outlines and supports wave-solder and hand-solder rework without risk of seal degradation.
Can the 5962-8869101RA be used as a drop-in replacement for SN54ALS520J?
Yes, the 5962-8869101RA is functionally and pinout-compatible with SN54ALS520J, sharing identical electrical specifications, timing parameters, and CDIP-J packaging. Both meet MIL-PRF-38535 Class B requirements and operate across –55°C to +125°C. The 5962-8869101RA is the standardized JAN (Joint Army-Navy) designation for this device, ensuring full interchangeability in defense logistics systems where 5962-8869101RA is the mandated procurement part number.
What is the maximum propagation delay for the 5962-8869101RA's P = Q output?
The worst-case propagation delay from any input (Pₙ or Qₙ) to the P = Q output is 25 ns for tPHL (high-to-low transition) and 19 ns for tPLH (low-to-high transition), measured under VCC = 4.5 V to 5.5 V, CL = 50 pF, and full temperature range. These values ensure the 5962-8869101RA meets timing closure in 40 MHz synchronous systems. The 5962-8869101RA's delay consistency across temperature and voltage makes it suitable for deterministic real-time decision logic.
