Product details
Overview
5962-9758501QRA from Texas Instruments is a military-grade octal buffer/driver IC with dual 4-bit noninverting 3-state outputs, designed for memory address buffering and bus driving in high-reliability systems. It operates over –55°C to 125°C, features 20-pin CDIP (J) package, supports 5 V supply, delivers ±48 mA output drive, and exhibits tPLH/tPHL ≤ 7 ns / ≤ 4.7 ns at 5 V.
For engineers reviewing the 5962-9758501QRA datasheet, 5962-9758501QRA pinout, 5962-9758501QRA application, or 5962-9758501QRA equivalent, this page provides verified functional specifications, military temperature validation, CDIP package details, 3-state bus interface behavior, and direct alternatives for legacy aerospace and defense designs.
Technical Context
The 5962-9758501QRA implements two independent 4-bit noninverting buffers, each controlled by an active-low output-enable (OE) input. Data flows from A inputs to Y outputs only when OE is low; otherwise, outputs enter high-impedance state-enabling bidirectional bus sharing without contention.
It uses TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V), delivers VOH ≥ 2.4 V at –12 mA, VOL ≤ 0.55 V at 48 mA, and maintains ICC ≤ 75 mA under full-output switching. Its absolute maximum ratings include VCC up to 7 V and input voltage range of –1.2 V to 7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V logic rails and margin against rail droop in ruggedized systems. |
| Operating Temperature | –55°C to 125°C - qualified for extended military and aerospace environments including avionics and ground vehicle control units. |
| Output Drive | ±48 mA per output - sufficient to drive 50 Ω transmission lines or multiple TTL loads without external buffering. |
| Propagation Delay | tPLH/tPHL ≤ 7 ns / ≤ 4.7 ns - enables reliable operation in sub-100 MHz address/data bus timing budgets. |
| 3-State Leakage | IOZL/IOZH ≤ ±50 µA - guarantees minimal bus leakage during high-impedance hold, critical for stable multi-driver arbitration. |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - matches standard TTL logic families, eliminating level-shifting requirements in legacy digital systems. |
Pinout & Package
5962-9758501QRA is housed in a 20-pin Ceramic Dual-In-Line Package (CDIP, J package), hermetically sealed for moisture resistance and long-term reliability in harsh environments. Pin spacing is 0.1 inch (2.54 mm), with standard DIP footprint compatible with MIL-STD-883 compliant board layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output-enable controls first and second 4-bit buffer sections independently. |
| 2–5, 11–14 | 1A1–1A4, 2A1–2A4 | Noninverting data inputs for each buffer section - directly connect to address or data bus lines. |
| 6–9, 15–18 | 1Y1–1Y4, 2Y1–2Y4 | 3-state buffered outputs - drive shared buses or memory address registers with controllable isolation. |
| 10 | GND | Signal ground reference for all I/O and internal logic - requires low-inductance connection to system ground plane. |
| 20 | VCC | +5 V power supply - must be decoupled locally with ≥0.1 µF ceramic capacitor near pin 20. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit buffers | Enables selective enabling of two address/data segments - reduces bus contention risk in modular memory architectures. |
| 3-state outputs with symmetrical OE | Allows seamless integration into multiplexed backplanes where multiple drivers share common traces without pull-up conflicts. |
| Military temperature qualification | Validated across –55°C to 125°C per MIL-PRF-38535 - eliminates thermal derating concerns in uncontrolled environmental deployments. |
| TTL-compatible input/output levels | Interoperates directly with legacy 74LS, 74F, and 74AS logic without level translators - preserves signal integrity in mixed-family systems. |
| High noise immunity | Input clamp current rating of –18 mA and VIK = –1.2 V - suppresses ESD transients and line reflections in noisy vehicular or industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/33201BRA | Identical electrical specs, same CDIP (J) package, identical military temperature range (–55°C to 125°C), but marked per JAN/DESC standard instead of 5962-series. | No functional difference; accepted interchangeably in DoD BOMs requiring QML-38535 Class V certification. | Select JM38510/33201BRA when procurement mandates JAN-standard marking or legacy DESC drawing compliance. |
| SNJ54F240J | Same die, same CDIP (J) package, same temperature range, but TI's internal military part number - no 5962 prefix or QML documentation package. | Used in earlier-generation systems; lacks formal 5962-9758501QRA traceability to MIL-PRF-38535 Rev G testing reports. | Choose SNJ54F240J only if existing qualification records already cover this variant and full 5962 documentation is not contractually required. |
Compared with 5962-9758501QRA, JM38510/33201BRA offers identical performance and packaging with alternate military marking, while SNJ54F240J provides functional equivalence but lacks the formal QML-38535 Rev G test report lineage required for new DoD hardware certifications.

FAQ
What is the operating temperature range of the 5962-9758501QRA?
The 5962-9758501QRA is characterized for operation from –55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This full military temperature range ensures reliable functionality in extreme environments such as jet engine bays, desert-deployed ground vehicles, and space payload compartments where passive thermal management prevails. All electrical parameters in the datasheet are guaranteed across this span without derating.
Does the 5962-9758501QRA support 3.3 V logic interfacing?
No, the 5962-9758501QRA is a 5 V TTL-family device with VIH = 2.0 V minimum and VIL = 0.8 V maximum - it does not guarantee correct operation with 3.3 V logic levels. Direct connection to 3.3 V microcontrollers or FPGAs requires level translation. The 5962-9758501QRA must be powered from a stable 5 V supply and driven by TTL- or 5 V CMOS-compatible sources to ensure valid input recognition and output drive compliance.
What package type is used for the 5962-9758501QRA?
The 5962-9758501QRA uses a 20-pin Ceramic Dual-In-Line Package (CDIP), designated as J package per TI's packaging nomenclature. This hermetically sealed ceramic package provides superior moisture resistance, thermal stability, and long-term reliability compared to plastic variants - essential for aerospace, defense, and industrial applications exposed to humidity, thermal cycling, or extended shelf life requirements.
How many independent buffer sections does the 5962-9758501QRA contain?
The 5962-9758501QRA contains two independent 4-bit noninverting buffer sections, each with its own active-low output-enable (OE) input (pins 1 and 19). This architecture allows selective activation of either group - for example, enabling one set of address lines while holding another in high-impedance - facilitating flexible bus segmentation and reducing contention in complex memory or peripheral interconnects.
Is the 5962-9758501QRA RoHS compliant?
The 5962-9758501QRA is not RoHS compliant in its standard configuration; it uses leaded solder and traditional ceramic DIP construction per MIL-PRF-38535 requirements. TI's packaging addendum confirms "Call TI" for lead finish, indicating Pb-based terminations. For RoHS-compliant alternatives, consider commercial-grade SN74F240 variants in SOIC or PDIP packages - but note these lack military temperature range and qualification.
