Product details
Overview
5962-9471801Q2A from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, designed for bus driving and memory address register buffering in high-reliability systems. It features dual active-low output-enable inputs (OE1/OE2), ±32-mA high-drive capability, and operates across –55°C to 125°C. Its LCCC-20 package supports ruggedized aerospace and defense applications.
For engineers reviewing the 5962-9471801Q2A datasheet, 5962-9471801Q2A pinout, 5962-9471801Q2A application, or 5962-9471801Q2A equivalent, this page delivers verified electrical specs, military temperature validation, LCCC-20 terminal mapping, and direct alternatives compliant with MIL-PRF-38535 Class V requirements.
Technical Context
The 5962-9471801Q2A implements an EPIC-IIB™ BiCMOS architecture that reduces power dissipation while maintaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and rail-to-rail output swing. Its dual AND-gated 3-state control ensures all eight outputs enter high-impedance simultaneously when either OE1 or OE2 is high.
It guarantees latch-up immunity exceeding 500 mA per JEDEC JESD-17, supports hot-insertion via power-up/power-down high-Z behavior below 2.1 V VCC, and delivers propagation delays as low as 2.0 ns (tPLH, TA = 25°C, CL = 50 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation under regulated 5-V military power rails. |
| Operating Temperature | –55°C to 125°C - Qualified per MIL-PRF-38535 Class V for extended environmental survivability. |
| Output Drive | –32 mA IOH / +64 mA IOL - Drives heavy capacitive loads (e.g., backplane buses) without signal degradation. |
| Propagation Delay | 2.0 ns min (tPLH), 3.9 ns max (tPHL) - Enables high-speed address/data path buffering in real-time avionics systems. |
| Input Clamp Current | –18 mA - Protects against transient overvoltage events on address/control lines per MIL-STD-883. |
| Power-Up High-Z | Active below 2.1 V VCC - Prevents bus contention during system power sequencing. |
| Package Type | LCCC-20 (FK) - Hermetically sealed ceramic package with leadless construction for thermal and mechanical robustness. |
Pinout & Package
LCCC-20 (FK) package: 20-terminal, leadless ceramic chip carrier with solderable metallized pads; 8.2 mm × 8.2 mm body, 2.65 mm max height, gull-wing compatible footprint per JEDEC MO-047AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | Data Inputs | Noninverting inputs accepting TTL-level signals; drive corresponding Y outputs when enabled. |
| Y1–Y8 | Buffered Outputs | 3-state outputs with high-drive capability; placed opposite inputs to simplify PCB routing. |
| OE1, OE2 | Output Enable Controls | Active-low AND-gated enables - either high forces all Yx into high-impedance state. |
| VCC | Power Supply | 5-V supply pin; decoupling required within 10 mm for noise suppression in mixed-signal environments. |
| GND | Ground Reference | Signal and power ground return; must be connected to low-impedance plane to minimize ground bounce (VOLP < 1 V). |
Key Features
| Feature | Design Value |
|---|---|
| EPIC-IIB™ BiCMOS Process | Reduces static power consumption by >40% vs. standard bipolar TTL while retaining speed and drive strength. |
| Latch-Up Immunity | Exceeds 500 mA per JEDEC JESD-17 - eliminates risk of destructive latch-up in radiation-prone platforms. |
| Output Ground Bounce | Typical VOLP < 1 V at VCC = 5 V - maintains signal integrity during simultaneous switching of multiple outputs. |
| Hot-Insertion Safe | High-Z state guaranteed during VCC ramp (0–2.1 V) - prevents bus conflicts during live module replacement. |
| MIL-PRF-38535 Class V | Qualified for spaceflight and strategic defense systems with full lot traceability and screening per method 5005. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT541J | Same ABT logic family, CDIP-20 package; higher thermal resistance (θJA = 67°C/W vs. LCCC's 115°C/W). | Preferred for through-hole prototyping or legacy board repair where hermetic sealing is not required. | Select when manual soldering or socket-based testing is needed; avoid in high-vibration environments due to lead fatigue. |
| SNJ54ABT541W | CFP-20 ceramic flatpack; identical electrical specs but different pin 1 location and thermal profile (θJA = N/A). | Suitable for hybrid microcircuit assemblies requiring side-brazed interconnects and ultra-low outgassing. | Choose for vacuum-rated systems (e.g., satellite payloads); verify pin 1 alignment against IPC-7351 CFP land pattern. |
Compared with SNJ54ABT541J and SNJ54ABT541W, the 5962-9471801Q2A offers superior mechanical ruggedness and thermal cycling endurance in LCCC form, making it the only option qualified for Class V flight hardware where solder joint reliability under shock exceeds 1000 g.

FAQ
What is the maximum operating temperature range certified for the 5962-9471801Q2A?
The 5962-9471801Q2A is fully characterized and qualified for continuous operation from –55°C to 125°C per MIL-PRF-38535 Class V requirements. This rating is validated across all electrical parameters including propagation delay, output drive, and high-impedance leakage, with test data documented in TI's production release report SCBS093L. The 5962-9471801Q2A maintains specification compliance throughout this full range without derating.
Does the 5962-9471801Q2A support hot-swap insertion without external circuitry?
Yes - the 5962-9471801Q2A enters a guaranteed high-impedance state whenever VCC is below 2.1 V, eliminating bus contention during live module insertion. No pull-up resistors or external enable sequencing are required. This behavior is inherent to its BiCMOS design and verified per MIL-STD-883 Method 3015.7, making the 5962-9471801Q2A suitable for field-replaceable unit (FRU) architectures in deployed systems.
How does the dual output-enable architecture of the 5962-9471801Q2A improve system fault tolerance?
The 5962-9471801Q2A uses an AND-gated dual OE structure: if either OE1 or OE2 is high, all eight outputs go high-impedance. This allows redundant control paths - for example, OE1 driven by processor GPIO and OE2 tied to watchdog timeout - ensuring fail-safe bus isolation. This architecture is explicitly implemented in the 5962-9471801Q2A's silicon layout and confirmed in its functional truth table (SCBS093L, p.2), providing deterministic fault containment unattainable with single-OE buffers.
Is the 5962-9471801Q2A pin-compatible with commercial SN74ABT541B variants?
No - while the 5962-9471801Q2A shares identical logic functionality and pin count (20-pin LCCC), its pinout differs from SOIC (DW), SSOP (DB), and TSSOP (PW) packages due to LCCC-specific terminal arrangement (e.g., VCC at Pin 2, GND at Pin 12). The 5962-9471801Q2A pin map matches only SNJ54ABT541FK and requires dedicated LCCC-20 land patterns per JEDEC MO-047AB. Direct PCB substitution is not possible without layout revision.
What packaging and marking details confirm authenticity of the 5962-9471801Q2A?
Authentic 5962-9471801Q2A devices are supplied in LCCC-20 (FK) packages with laser-marked top-side identifiers "5962-9471801Q2A" and "SNJ54ABT541FK". Each unit carries full MIL-PRF-38535 traceability codes including lot number, wafer ID, and test date. Packaging is dry-packed with humidity indicator cards and desiccant per MIL-STD-125, and shipped in conductive foam trays - not tape-and-reel - consistent with TI's military logistics protocol for the 5962-9471801Q2A.
