Product details
Overview
5962-9318801MSA from Texas Instruments is a military-grade octal inverting buffer/driver with 3-state outputs, designed for high-density bus interfacing in aerospace and defense systems. It features –32-mA high-drive IOH, 64-mA IOL output capability, Ioff partial-power-down support, and operates across –55°C to 125°C. It is used in memory address buffering and clock distribution where latch-up immunity (>500 mA per JESD-17) and ESD robustness (2000-V HBM) are critical.
For engineers reviewing the 5962-9318801MSA datasheet, 5962-9318801MSA pinout, 5962-9318801MSA application, or 5962-9318801MSA equivalent, key selection criteria include its CFP (W) package, dual 4-bit inverting architecture with independent OE controls, guaranteed operation under extended temperature extremes, and compatibility with legacy ABT logic families in radiation-tolerant or high-reliability platforms.
Technical Context
The 5962-9318801MSA implements two independent 4-bit inverting buffer sections, each with dedicated active-low output-enable (OE) inputs. Data propagates from A inputs to Y outputs only when OE is low; outputs enter high-impedance state when OE is high.
It uses TI's ABT logic family architecture with bipolar-TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V), rail-to-rail output swing (VOH ≥ 2.0 V at –32 mA, VOL ≤ 0.55 V at 64 mA), and integrated Ioff circuitry that disables outputs during power-down to prevent backflow current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal inverting buffer/driver with dual independent 4-bit sections and separate OE controls |
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5-V TTL and ABT system rails |
| Output Drive | –32 mA IOH / 64 mA IOL - supports heavy capacitive loads and fan-out to multiple CMOS/TTL inputs |
| Operating Temperature | –55°C to 125°C - qualified for military/aerospace applications per MIL-PRF-38535 |
| Ioff Support | Enables safe partial-power-down operation - prevents damaging current flow when VCC = 0 V |
| Propagation Delay | tPLH/tPHL ≤ 4.8 ns (VCC = 5 V, CL = 50 pF) - enables high-speed bus buffering in real-time control systems |
| ESD Rating | 2000-V HBM, 200-V MM - meets stringent electrostatic discharge requirements for field-deployable hardware |
Pinout & Package
5962-9318801MSA is housed in a 20-pin Ceramic Flatpack (CFP-W) package, hermetically sealed for high-reliability environments. The package has a 0.51-mm lead pitch, 13.0-mm × 7.6-mm body, and 2.65-mm max height, suitable for ruggedized PCB layouts and conformal coating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-Low Output Enable | Controls high-impedance state for respective 4-bit section - must be pulled high via resistor during power sequencing to ensure defined startup state |
| 1A1–1A4, 2A1–2A4 | Input | Inverting data inputs for each buffer section - compatible with TTL/CMOS logic levels and supports hot-insertion with Ioff |
| 1Y1–1Y4, 2Y1–2Y4 | Inverting Output | High-drive buffered outputs - capable of sinking 64 mA or sourcing –32 mA while maintaining VOH/VOL specs |
| VCC | Power Supply | 5-V nominal supply - requires local decoupling due to fast edge rates and ground bounce sensitivity (VOLP < 1 V) |
| GND | Ground Reference | Common return path for all signals and power - critical for noise suppression in mixed-signal avionics subsystems |
Key Features
| Feature | Design Value |
|---|---|
| High-Drive Outputs | –32 mA source / 64 mA sink capability enables direct driving of unterminated transmission lines or multiple downstream loads without external buffers |
| Ioff Partial-Power-Down | Outputs automatically disable when VCC = 0 V, eliminating risk of backfeed current in hot-swap or phased-power architectures |
| Latch-Up Immunity | Exceeds 500 mA per JEDEC JESD-17 - ensures survivability in high-noise launch or radar environments |
| Ground Bounce Control | Typical VOLP < 1 V at 5 V/25°C - reduces signal integrity degradation in dense multi-buffer layouts |
| MIL-PRF-38535 Compliance | Fully tested per Class V requirements - includes screening for burn-in, temperature cycling, and hermeticity verification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT240J | Same ABT240 function and electrical specs; packaged in 20-pin CDIP (J) instead of CFP (W) | CDIP offers lower cost and easier prototyping but lacks hermetic seal and thermal performance of CFP | Select SNJ54ABT240J for lab validation or non-hermetic ground-based systems where cost and solderability are prioritized |
| 5962-9318801M2A | Identical function and temperature range; uses 20-pin LCCC (FK) package with leadless ceramic construction | LCCC provides superior high-frequency performance and thermal dissipation but requires specialized rework and inspection | Choose 5962-9318801M2A for space-constrained, high-frequency avionics where minimal parasitic inductance is essential |
Compared with SNJ54ABT240J and 5962-9318801M2A, the 5962-9318801MSA delivers optimal balance of hermetic reliability, thermal stability, and manufacturability in CFP-W - making it preferred for deployed airborne platforms requiring long-term field endurance.

The 5962-9318801MSA is rated for operation from –55°C to 125°C, fully compliant with MIL-PRF-38535 Class V requirements. This range is validated through temperature cycling, burn-in, and parametric testing across extremes, making the 5962-9318801MSA suitable for deployment in jet engine bays, space payloads, and artillery fire-control systems where ambient conditions exceed commercial limits.
Does the 5962-9318801MSA support partial-power-down operation?
Yes, the 5962-9318801MSA incorporates Ioff circuitry that actively disables outputs when VCC = 0 V, preventing damaging backflow current during power sequencing or hot-swap events. This feature is confirmed in the datasheet's "description (continued)" section and is critical for use in phased-power avionics architectures where subsystems power up/down independently - ensuring the 5962-9318801MSA remains safe and functional even when unpowered.
What package type is used for the 5962-9318801MSA?
The 5962-9318801MSA uses a 20-pin Ceramic Flatpack (CFP-W) package, identified by TI's package drawing W. It features a hermetically sealed ceramic body, 0.51-mm lead pitch, and 13.0 mm × 7.6 mm footprint. This package is explicitly listed in TI's Packaging Information Addendum for 5962-9318801MSA and is optimized for high-reliability applications requiring moisture resistance and thermal stability - distinguishing the 5962-9318801MSA from plastic-packaged ABT240 variants.
How does the 5962-9318801MSA differ from commercial SN74ABT240A devices?
The 5962-9318801MSA is the military-specification version of the SN74ABT240A, manufactured to MIL-PRF-38535 standards with full screening (including burn-in, temperature cycling, and hermeticity tests), extended –55°C to 125°C operation, and CFP-W packaging. Unlike commercial SN74ABT240A variants, the 5962-9318801MSA guarantees performance under extreme environmental stress and includes lot traceability and failure analysis support - confirming its qualification for life-critical defense systems.
What are the absolute maximum ratings for the 5962-9318801MSA?
The 5962-9318801MSA has an absolute maximum supply voltage of –0.5 V to 7 V, input/output voltage range of –0.5 V to 7 V (or –0.5 V to 5.5 V on outputs in high-Z/power-off), and output current limit of 96 mA for the SN54ABT240 variant (which the 5962-9318801MSA implements). These ratings are documented in the "absolute maximum ratings" table of the SCBS098I datasheet and define safe operating boundaries beyond which permanent device damage may occur - critical for designing overvoltage protection in 5962-9318801MSA-based systems.
