Product details
Overview
5962-9318801MRA 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, Ioff partial-power-down support, latch-up immunity >500 mA per JESD-17, and operates across –55°C to 125°C in CDIP-J package.
For engineers reviewing the 5962-9318801MRA datasheet, 5962-9318801MRA pinout, 5962-9318801MRA application, or 5962-9318801MRA equivalent, key selection criteria include its MIL-PRF-38535 compliance, guaranteed operation over extended temperature, high-current drive capability, and Ioff-enabled system-level power sequencing in mixed-voltage environments.
Technical Context
The 5962-9318801MRA implements two independent 4-bit inverting buffer sections, each with dedicated active-low output-enable (OE) inputs. Its ABT logic family delivers TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) and rail-to-rail output swing under load.
It supports true partial-power-down via Ioff circuitry that disables outputs when VCC = 0 V, limiting reverse current to ±100 µA. Output switching is characterized at CL = 50 pF, with tPLH/tPHL ≤ 4.8 ns and enable/disable times (tPZH/tPLZ) ≤ 7.7 ns at VCC = 5 V and TA = 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal inverting buffer with dual 4-bit sections and independent OE control |
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with 5-V TTL and mixed-signal systems |
| Output Drive | –32 mA IOH / 64 mA IOL - enables direct driving of heavy capacitive loads or multiple TTL inputs |
| Ioff Support | ±100 µA max at VCC = 0 - prevents backflow during hot-insertion or staggered power sequencing |
| Operating Temperature | –55°C to 125°C - qualified for military/aerospace platforms per MIL-PRF-38535 |
| Package | 20-pin Ceramic Dual In-line Package (CDIP-J) - hermetic, leaded, and board-mount compatible |
| Propagation Delay | tPLH/tPHL ≤ 4.8 ns @ CL = 50 pF - supports high-speed address/data bus timing in real-time avionics |
Pinout & Package
5962-9318801MRA is housed in a 20-pin hermetic Ceramic Dual In-line Package (CDIP-J), compliant with MIL-STD-1835 and JEDEC MS-001. The package provides mechanical robustness, thermal stability, and long-term reliability in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low output-enable inputs | Enable/disable respective 4-bit buffer sections independently; tie to VCC via pullup for power-up high-Z safety |
| 1A1–1A4, 2A1–2A4 | Input terminals | Invert and propagate to corresponding Y outputs when OE is low; TTL-compatible thresholds |
| 1Y1–1Y4, 2Y1–2Y4 | Inverting buffered outputs | Drive external buses or memory address lines; high-impedance when OE is high |
| VCC | Positive supply | 4.5–5.5 V nominal; powers internal logic and output drivers |
| GND | Signal reference | Return path for all inputs, outputs, and internal circuitry; must be low-inductance connection |
Key Features
| Feature | Design Value |
|---|---|
| High-Drive Outputs | –32 mA IOH / 64 mA IOL enables fanout to ≥10 standard TTL loads without buffering |
| Ioff Partial-Power-Down | Prevents damaging current flow when powered down, supporting safe hot-swap and power sequencing |
| Latch-Up Immunity | Exceeds 500 mA per JESD-17 - critical for mission-critical systems exposed to ESD or transient events |
| MIL-PRF-38535 Compliance | Full screening including radiation hardness assurance, burn-in, and lot traceability for defense applications |
| Low Ground Bounce | VOLP < 1 V at VCC = 5 V - maintains signal integrity during simultaneous output switching |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54ABT240FK | LCCC-FK package (20-pin ceramic leadless chip carrier); identical electrical specs and temperature range | Better high-frequency performance due to lower inductance; requires reflow-compatible PCB layout | Select when board space is constrained and surface-mount assembly is preferred over through-hole CDIP |

FAQ
What is the operating temperature range for the 5962-9318801MRA?
The 5962-9318801MRA is fully specified from –55°C to 125°C and qualified per MIL-PRF-38535, making it suitable for deployment in extreme environmental conditions typical of aerospace, defense, and downhole instrumentation applications. All parameters in its datasheet are tested across this full range on products compliant to that specification.
Does the 5962-9318801MRA support partial-power-down functionality?
Yes, the 5962-9318801MRA includes Ioff circuitry that disables outputs when VCC = 0 V, limiting reverse current to ±100 µA. This feature allows safe insertion into live backplanes and supports controlled power sequencing in multi-rail systems-critical for fault-tolerant 5962-9318801MRA deployments.
What package type is used for the 5962-9318801MRA?
The 5962-9318801MRA uses a 20-pin Ceramic Dual In-line Package (CDIP-J), a hermetically sealed, through-hole mount package with tin-lead leads. It complies with MIL-STD-1835 and JEDEC MS-001, offering superior moisture resistance and long-term reliability in demanding operational environments.
How does the 5962-9318801MRA handle output enable during power-up?
To ensure high-impedance state at power-up or power-down, the OE inputs of the 5962-9318801MRA should be tied to VCC through a pullup resistor. The minimum value depends on the driver's current-sinking capability; TI recommends values between 1 kΩ and 10 kΩ for robust noise immunity and fast transition control in 5962-9318801MRA systems.
Is the 5962-9318801MRA pin-compatible with commercial-grade SN74ABT240A variants?
No-the 5962-9318801MRA shares identical pinout and logic function with SN74ABT240A but differs in screening, packaging, and qualification. While electrically compatible, its CDIP-J package and MIL-PRF-38535 testing require separate layout and procurement handling; it is not a drop-in replacement for commercial SOIC or SSOP variants like SN74ABT240ADBR.
