Product details
Overview
5962-9471801QRA from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, designed for high-reliability bus interfacing in aerospace and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs (IOH/IOL), features dual active-low output-enable inputs (OE1/OE2), and uses EPIC-IIB™ BiCMOS technology for low power dissipation.
For engineers reviewing the 5962-9471801QRA datasheet, 5962-9471801QRA pinout, 5962-9471801QRA application, or 5962-9471801QRA equivalent, this device is selected for mission-critical address/data buffering where latch-up immunity (>500 mA per JESD-17), controlled power-up/down high-impedance behavior, and ground-bounce suppression (<1 V VOLP at 5 V) are required.
Technical Context
The 5962-9471801QRA implements an octal noninverting buffer architecture with independent 3-state control via two AND-gated OE inputs (active-low). Its EPIC-IIB™ BiCMOS process enables TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) while supporting 4.5–5.5 V supply operation and delivering rail-to-rail output swing under load.
During power transitions (VCC 0–2.1 V), all outputs enter high-impedance state without external bias; above 2.1 V, OE pins must be pulled to VCC for guaranteed disable. Propagation delays are tightly controlled: tPLH/tPHL ≤ 4.7 ns (max) and output skew tsk(o) ≤ 0.5 ns at CL = 50 pF and TA = 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V TTL and CMOS logic rails. |
| Operating Temperature | –55°C to 125°C - Qualified per MIL-PRF-38535 for extended-range military and space applications. |
| Output Drive | –32 mA IOH / +64 mA IOL - Sustains robust signal integrity driving heavy capacitive loads or multiple TTL inputs. |
| Propagation Delay | ≤ 4.7 ns (tPHL/tPLH max at VCC = 5 V, CL = 50 pF) - Enables reliable timing in high-speed address/data buses up to ~200 MHz. |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - Matches standard TTL logic levels for seamless interface with legacy systems. |
| Ground Bounce | VOLP < 1 V at VCC = 5 V, TA = 25°C - Minimizes noise coupling during simultaneous output switching. |
| Latch-Up Immunity | >500 mA per JESD-17 - Guarantees survivability under transient fault conditions in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT541FK | LCCC-20 ceramic package; identical electrical specs but different thermal profile (θJA ≈ 120°C/W vs. CDIP's 67°C/W) and mounting method. | Preferred for surface-mount board assemblies requiring higher vibration resistance and lower profile than through-hole CDIP. | Select SNJ54ABT541FK when PCB real estate or mechanical ruggedness outweighs through-hole assembly preference. |
| SNJ54ABT541W | CFP-20 ceramic flatpack; same temperature range and drive strength, but smaller footprint and no leads-requires specialized soldering. | Used in ultra-dense, high-frequency modules where lead inductance must be minimized and hermeticity remains essential. | Choose SNJ54ABT541W only when system-level RF performance or miniaturization mandates leadless packaging. |
Compared with SNJ54ABT541FK and SNJ54ABT541W, the 5962-9471801QRA offers optimal trade-off between ease of through-hole prototyping, proven field reliability in legacy avionics, and thermal performance-making it the default choice for new designs targeting CDIP-based qualification paths.

FAQ
What is the operating temperature range of the 5962-9471801QRA?
The 5962-9471801QRA is fully characterized for operation from –55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. This range is validated across all electrical parameters including propagation delay, drive strength, and 3-state leakage, making it suitable for deployment in uncontrolled environmental enclosures aboard aircraft, missiles, and satellites.
Does the 5962-9471801QRA require external pull-up resistors on OE pins?
Yes - while the 5962-9471801QRA enters high-impedance state automatically when VCC is below 2.1 V, OE1 and OE2 must be actively pulled to VCC via external resistors above that threshold to guarantee disable. TI recommends a resistor value ≤10 kΩ to ensure sufficient current sinking capability against the driver's input leakage (±1 µA).
Is the 5962-9471801QRA RoHS-compliant?
No - the 5962-9471801QRA is a legacy military-spec CDIP (J-package) with leaded finish and is not RoHS-compliant. It follows MIL-STD-19500 and MIL-PRF-38535 requirements, which permit leaded terminations for enhanced solder joint reliability in high-vibration and thermal-cycling applications.
How does the dual OE architecture of the 5962-9471801QRA improve system design?
The dual OE inputs (OE1 for Y1–Y4, OE2 for Y5–Y8) allow independent control of two logical bus segments using a single 5962-9471801QRA. This eliminates need for discrete gating logic, reduces gate count, and enables precise timing isolation - for example, disabling memory address lines while keeping data lines active during burst transfers.
What is the maximum capacitive load the 5962-9471801QRA can drive reliably?
The 5962-9471801QRA is specified with CL = 50 pF for switching characterization, but its ±32-mA/±64-mA drive strength supports heavier loads. In practice, it reliably drives up to 100 pF with <5 ns added delay and maintains VOL < 0.55 V at IOL = 64 mA - verified in TI's application report SCBA004 for high-fanout bus scenarios.
