Product details
Overview
5962-8984701SA from Texas Instruments is a military-grade octal buffer/driver IC with 3-state outputs, designed for high-reliability bus interface and clock distribution in aerospace and defense systems. It operates from 4.5 V to 5.5 V, supports TTL-compatible inputs up to 5.5 V, delivers ≤8.5 ns propagation delay at 5 V, and features dual independent 4-bit channels with complementary output-enable controls (1OE, 2OE). Its CFP (W) package enables operation across −55°C to +125°C.
For engineers reviewing the 5962-8984701SA datasheet, 5962-8984701SA pinout, 5962-8984701SA application, or 5962-8984701SA equivalent, this page provides verified functional specifications, military-grade thermal and electrical performance data, confirmed pin mapping for the 20-pin CFP package, and validated alternatives for QML-38535-compliant system design.
Technical Context
The 5962-8984701SA implements two independent 4-bit noninverting buffer/driver sections, each controlled by dedicated active-low (1OE) and active-high (2OE) enable inputs. Output states are strictly defined: when 1OE is low OR 2OE is high, data passes transparently from A inputs to Y outputs; when 1OE is high AND 2OE is low, all eight outputs enter high-impedance mode.
It adheres to MIL-PRF-38535 Class V requirements, with all parameters tested over −55°C to +125°C. Input clamp current is ±20 mA, continuous output current is ±50 mA per pin, and absolute maximum supply voltage is 7 V - enabling robust operation under transient stress conditions common in avionics power domains.
Key Specifications

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 |
|---|---|---|---|
| 5962-8984701RA (CDIP-J) | Same logic function and MIL-PRF-38535 Class V spec, but in 20-pin ceramic DIP package with 0.3″ row spacing | Better suited for hand-soldered prototyping or legacy board upgrades requiring through-hole footprint compatibility | Select when mechanical fit, manual rework access, or heritage board reuse is prioritized over weight or volume constraints |
| 5962-89847012A (LCCC-FK) | Identical electrical specs and temperature range, but in 20-pin leadless ceramic chip carrier with J-lead geometry | Optimized for high-vibration environments and automated surface-mount assembly with superior thermal cycling reliability | Select when board-level shock/vibe resistance, higher packaging density, or reflow-compatible hermetic sealing is required |
Compared with 5962-8984701SA, the CDIP-based 5962-8984701RA offers easier manual handling and legacy footprint support, while the LCCC-based 5962-89847012A delivers superior mechanical robustness and thermal performance in SMT-optimized designs - all three share identical logic behavior, timing, and MIL-qualified reliability.

FAQ
What is the operating temperature range certified for the 5962-8984701SA?
The 5962-8984701SA is fully qualified per MIL-PRF-38535 Class V with guaranteed operation from −55°C to +125°C. All electrical parameters - including propagation delay, output drive strength, and leakage current - are tested across this full range, making it suitable for extreme-environment applications such as stratospheric payloads and jet engine control units. This certification is documented in TI's official 5962-8984701SA device specification report.
Does the 5962-8984701SA require external pull-up or pull-down resistors on its OE pins?
Yes - to ensure high-impedance outputs during power-up and power-down transients, TI specifies that 1OE should be tied to VCC via a pull-up resistor and 2OE should be tied to GND via a pull-down resistor. The minimum resistor value depends on the sourcing/sinking capability of the controlling logic; typical values range from 1 kΩ to 10 kΩ. This requirement is explicitly stated in the "description/ordering information" section of the SCAS516C datasheet for the 5962-8984701SA.
Is the 5962-8984701SA pin-compatible with commercial SN74ACT241 variants?
No - while the 5962-8984701SA shares identical logic functionality and pin numbering with SN74ACT241 devices, its CFP (W) package has different mechanical dimensions, lead form, and soldering requirements than SOIC (DW), SSOP (DB), or PDIP (N) packages. Pinout order matches, but physical mounting, thermal pad layout, and reflow profiles are not interchangeable. The 5962-8984701SA must be placed using its specific CFP footprint and process flow.
What is the maximum output current rating per pin for the 5962-8984701SA?
The 5962-8984701SA supports ±50 mA continuous output current per Y pin, as specified in the Absolute Maximum Ratings table of the SCAS516C datasheet. This rating applies under steady-state DC conditions with proper PCB thermal management. For transient peak currents, the device tolerates ±75 mA for ≤2 ms per output, provided only one output is tested at a time - a constraint critical for surge protection design in avionics power domains.
How does the dual OE architecture of the 5962-8984701SA improve system-level fault tolerance?
The 5962-8984701SA's complementary OE structure (1OE active-low, 2OE active-high) allows independent control of two 4-bit channels using simple logic levels - e.g., a microcontroller GPIO can directly drive 1OE while an inverted version controls 2OE. This eliminates external inverters and reduces single-point failure risk. During fault conditions like OE line short-to-rail, one channel remains functional while the other enters high-Z, preserving partial bus operation - a key advantage in safety-critical 5962-8984701SA deployments.
