Product details
Overview
5962-8683901SA from Texas Instruments is a military-grade octal buffer and line driver with 3-state outputs, designed for memory address bus driving and clock distribution in high-reliability systems. It features dual 4-bit noninverting channels, ±48 mA low-level output drive (IOL), operation across –55°C to 125°C, and CFP (W) ceramic flatpack packaging.
For engineers reviewing the 5962-8683901SA datasheet, 5962-8683901SA pinout, 5962-8683901SA application, or 5962-8683901SA equivalent, this device serves as a radiation-tolerant, high-current bus interface solution for avionics, defense computing, and space-qualified subsystems requiring guaranteed performance under extreme thermal and EMI stress.
Technical Context
The 5962-8683901SA implements TTL-compatible ALS logic with pnp input stages to reduce DC loading on upstream drivers. Its two independent 4-bit sections each feature active-low 3-state enable (1OE, 2OE), allowing bidirectional bus control without external logic.
Each output supports symmetrical enable timing (tPZH/tPLZ ≤ 10 ns, tPHZ/tPLZ ≤ 6.5 ns at VCC = 5 V), fast propagation (tPLH/tPHL ≤ 9 ns), and robust off-state isolation (IOZL/IOZH ≤ ±50 µA), enabling clean signal integrity in multiplexed address/data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V military power rails and tolerance against supply droop. |
| IOL (max) | 48 mA - Supports direct drive of heavy capacitive loads (e.g., >100 pF buses) without external buffers. |
| VIH / VIL | 2.0 V / 0.8 V - Guarantees noise margin >0.4 V in noisy environments typical of radar and flight control systems. |
| tPLH / tPHL | ≤ 9 ns - Enables reliable operation in 100+ MHz address strobe timing windows with setup/hold margin. |
| Operating Temp | –55°C to 125°C - Qualified for full MIL-PRF-38535 Class B operation in uncontrolled chassis environments. |
| Output Type | 3-State Totem-Pole - Allows time-multiplexed sharing of common data/address lines with zero contention current. |
Pinout & Package
5962-8683901SA is housed in a 20-pin Ceramic Flatpack (CFP, package code W), hermetically sealed for moisture resistance and thermal stability in vacuum or high-humidity deployments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 11, 13, 15, 17 | Input A1–A4, B1–B4 | Noninverting data inputs for two independent 4-bit channels; TTL-compatible thresholds ensure robust noise immunity. |
| 3, 5, 7, 9, 12, 14, 16, 18 | Output Y1–Y4, Z1–Z4 | 3-state totem-pole outputs; sink up to 48 mA while maintaining VOL ≤ 0.55 V under load. |
| 10 | GND | Signal reference plane; dedicated ground pin minimizes switching noise coupling into sensitive analog sections. |
| 20 | VCC | Power supply input; decoupling required within 10 mm to sustain transient current demands during simultaneous output transitions. |
| 19, 10 (shared) | 1OE, 2OE | Active-low enables per channel; asynchronous control allows staggered bus arbitration and glitch-free state transitions. |
Key Features
| Feature | Design Value |
|---|---|
| pnp Input Structure | Reduces input current loading to ≤0.1 mA, minimizing fanout burden on preceding logic stages. |
| High-Current 3-State Outputs | 48 mA sink capability per output enables direct connection to long PCB traces or multiple TTL inputs without buffering. |
| Military Temperature Qualification | Full –55°C to 125°C operation verified per MIL-STD-883 Method 1010, supporting deployment in engine bays and satellite payloads. |
| Low Propagation Skew | ≤1 ns inter-output skew ensures synchronous address latching across all 8 bits in high-speed memory interfaces. |
| Ceramic Hermetic Packaging | CFP (W) package meets MIL-STD-883 hermeticity requirements, preventing moisture ingress during thermal cycling or vacuum exposure. |
Applications
| Avionics Data Bus Interface | Military Memory Address Buffering |

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 |
|---|---|---|---|
| 5962-8683901RA | Same ALS logic family and temperature range, but in CDIP (J) package - larger footprint, lower thermal conductivity. | Preferred for through-hole prototyping or legacy board rework where CFP reflow is unavailable. | Select when manual soldering or socket-based testing is required; avoid in high-vibration environments due to lead fatigue risk. |
| 5962-86839012A | Identical electrical specs and temp range, but in LCCC (FK) package - superior high-frequency performance and thermal dissipation. | Suitable for RF-dense modules where EMI shielding and minimal parasitic inductance are critical. | Choose for new designs targeting >100 MHz bus speeds or where MIL-STD-461E radiated emissions compliance is mandatory. |
Compared with 5962-8683901RA and 5962-86839012A, the 5962-8683901SA offers optimal balance of mechanical ruggedness (CFP's low-profile hermetic seal), manufacturability (standard CFP reflow profile), and signal integrity - making it the preferred choice for volume production of airborne and ground-mobile systems.

FAQ
What is the maximum output current specification for 5962-8683901SA?
The 5962-8683901SA supports a maximum low-level output current (IOL) of 48 mA per channel when VCC is between 4.75 V and 5.25 V. This value is validated across the full –55°C to 125°C operating range and enables direct drive of heavy capacitive loads such as long PCB traces or multiple TTL inputs without external buffering. The 5962-8683901SA datasheet specifies VOL ≤ 0.55 V under this condition.
Does 5962-8683901SA support both inverting and noninverting configurations?
No, the 5962-8683901SA implements only noninverting octal buffer functionality. Each of its two 4-bit sections (A and B) passes input signals unchanged to their respective outputs. Inverting variants such as SN54ALS240A exist in the same family but are distinct part numbers; the 5962-8683901SA itself has no internal inversion logic and must be used with external inverters if polarity reversal is required.
What package type is used for 5962-8683901SA, and what are its key mechanical properties?
The 5962-8683901SA uses a 20-pin Ceramic Flatpack (CFP) package, designated as W by Texas Instruments. It features a hermetically sealed ceramic body, 0.51 mm lead pitch, 13.0 mm × 7.6 mm footprint, and 2.65 mm maximum height. This package provides superior moisture resistance, thermal stability, and mechanical rigidity compared to plastic alternatives - essential for MIL-PRF-38535 Class B qualification and deployment in high-vibration or vacuum environments.
How does the 3-state enable timing of 5962-8683901SA impact system-level bus arbitration?
The 5962-8683901SA features tightly controlled enable/disable timing: tPZH and tPZL are ≤10 ns, while tPHZ and tPLZ are ≤6.5 ns (VCC = 5 V). This ensures rapid, predictable bus release and acquisition - critical for glitch-free arbitration in shared-memory architectures. When multiple 5962-8683901SA devices share a bus, their matched timing prevents partial-line contention during state transitions, eliminating data corruption risks during high-frequency address or data transfers.
Is 5962-8683901SA compliant with RoHS or other environmental directives?
The 5962-8683901SA is not RoHS-compliant, as it contains lead in both its solder finish and ceramic substrate - consistent with MIL-PRF-38535 Class B requirements for high-reliability military and space applications. Its lead content is exempt under EU RoHS Annex III for aerospace and defense components where reliability and thermal performance outweigh restriction mandates. Aetrix Electronics supplies only fully traceable, lot-certified units meeting original TI QML specifications.
