Product details
Overview
5962-9075201MRA from Texas Instruments is a military-grade 8-bit non-inverting bus transceiver with direction control (DIR) and output enable (OE), designed for asynchronous bidirectional data transfer between A and B buses in high-reliability systems. It operates across −55°C to 125°C, supports 5 V supply, delivers ±64 mA B-port drive, and features undershoot-protection circuitry and power-up high-impedance state.
For engineers reviewing the 5962-9075201MRA datasheet, 5962-9075201MRA pinout, 5962-9075201MRA application, or 5962-9075201MRA equivalent, this device is selected for MIL-STD-883-compliant digital interface isolation, radiation-tolerant avionics backplanes, and legacy military data bus bridging where BiCMOS speed, ESD robustness (>2000 V), and wide-temperature operation are mandatory.
Technical Context
The 5962-9075201MRA implements a dual-bus transceiver architecture with separate A- and B-port I/Os, DIR-controlled signal flow direction, and OE-gated three-state outputs. Its BiCMOS design enables TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and CMOS-level output drive capability while reducing standby current versus pure bipolar implementations.
It features buffered control inputs to minimize DC loading, undershoot-protection on all outputs, and guaranteed switching performance (tPLH ≤ 7 ns, tPHL ≤ 3.8 ns) under 50 pF load at VCC = 4.5–5.5 V and full military temperature range. Absolute maximum ratings include −0.5 V to 5.5 V I/O voltage and −55°C to 125°C operating free-air temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V logic rails and tolerance to supply ripple in harsh environments. |
| Operating Temperature | −55°C to 125°C - Qualified per MIL-PRF-38535 for use in airborne, spaceborne, and ground vehicle electronics. |
| B-Port Low-Level Drive (IOL) | 64 mA - Supports direct connection to multiple TTL loads without external buffers in legacy bus systems. |
| Propagation Delay (tPLH/tPHL) | ≤ 7 ns / ≤ 3.8 ns - Enables reliable timing in 20+ MHz synchronous bus interfaces with margin for trace skew. |
| ESD Protection | >2000 V per MIL-STD-883C, Method 3015 - Provides robust handling integrity during manual assembly and field maintenance. |
| Output Isolation (ICCZ) | 4–11 mA - Confirms low quiescent current in disabled (OE = high) state, critical for power-constrained platforms. |
| Input Clamp Current (IIK) | −18 mA - Specifies safe current-sinking capability during input overvoltage events, supporting fault-tolerant design. |
Pinout & Package
5962-9075201MRA is supplied in a 20-pin Ceramic Dual-In-Line Package (CDIP, J package), hermetically sealed for moisture resistance and long-term reliability in military applications. The package has 0.3-inch body width, 0.1-inch lead pitch, and meets MIL-STD-883 requirements for mechanical and environmental stress screening.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | A-port inputs/outputs | Bidirectional data lines connected to source bus; driven high/low or placed in high-Z based on DIR and OE. |
| 9 | GND | Signal reference and return path for all I/O and internal logic; requires low-inductance grounding in noise-sensitive systems. |
| 10 | VCC | +5 V power supply; must be decoupled locally with ≥0.1 µF ceramic capacitor to suppress switching noise. |
| 11 | OE (Output Enable) | Active-low control: when high, forces all A- and B-port outputs into high-impedance state for bus isolation. |
| 12, 13, 14, 15, 16, 17, 18, 19 | B-port inputs/outputs | Bidirectional data lines connected to destination bus; direction relative to A-port determined by DIR state. |
| 20 | DIR (Direction Control) | Controls data flow: low = B→A, high = A→B; sampled synchronously with OE to avoid bus contention. |
Key Features
| Feature | Design Value |
|---|---|
| State-of-the-art BiCMOS design | Reduces standby ICC by >50% vs. equivalent bipolar transceivers, lowering thermal load in sealed enclosures. |
| Undershoot-protection circuitry | Prevents negative voltage excursions below −0.5 V on B-port outputs during fast edge transitions, protecting downstream receivers. |
| Power-up high-impedance state | Guarantees no bus contention during system reset or cold start, eliminating need for external pull-up/pull-down networks. |
| Buffered control inputs | Reduces input loading to ≤0.1 mA at VI = 5.5 V, enabling direct fanout to ≥20 similar devices without buffering. |
| MIL-STD-883 qualified | Includes screening for burn-in, temperature cycling, and mechanical shock-required for DoD procurement and flight hardware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9075201M2A | LCCC (FK) package instead of CDIP (J); identical electrical specs and temperature range. | Better thermal dissipation and higher vibration resistance; used where board space is constrained but solder joint reliability is critical. | Select when surface-mount assembly and superior mechanical ruggedness are prioritized over through-hole mounting. |
| SNJ54BCT640J | Same CDIP (J) package and military temp range; identical pinout and function but lacks QML-38535 certification documentation traceability. | Approved for non-flight-critical ground systems; not accepted for spaceflight or certified airborne platforms requiring full QML pedigree. | Choose only for cost-sensitive defense logistics applications where full QML-38535 documentation is not contractually mandated. |
Compared with 5962-9075201MRA, the 5962-9075201M2A offers superior mountability in high-vibration environments, while SNJ54BCT640J provides functional equivalence at lower documentation overhead-but neither matches the full QML-38535 traceability and screening rigor of 5962-9075201MRA for flight-critical use.

FAQ
What is the operating temperature range of the 5962-9075201MRA?
The 5962-9075201MRA is characterized for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This range is validated across all electrical parameters including propagation delay, drive strength, and input thresholds, making it suitable for engine-mounted avionics and space-qualified electronics where ambient extremes are routine.
Does the 5962-9075201MRA support 3.3 V logic levels?
No, the 5962-9075201MRA is designed exclusively for 5 V operation, with recommended VCC of 4.5–5.5 V and TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V). It does not guarantee functionality or timing at 3.3 V supply or input levels, and interfacing with 3.3 V systems requires level-shifting circuitry external to the 5962-9075201MRA.
Is the 5962-9075201MRA pin-compatible with commercial SN74BCT640 variants?
Yes, the 5962-9075201MRA shares identical pinout and function with SN74BCT640 in PDIP (N) and SOIC (DW) packages, including DIR, OE, A1–A8, B1–B8, VCC, and GND assignments. However, its CDIP (J) package differs mechanically from commercial plastic DIPs, requiring dedicated footprint and reflow profile validation.
What packaging standard does the 5962-9075201MRA meet?
The 5962-9075201MRA is supplied in a 20-pin Ceramic Dual-In-Line Package (CDIP, J package) compliant with MIL-STD-1835 and screened per MIL-STD-883. Its hermetic seal, gold-plated leads, and ceramic body ensure long-term reliability in high-humidity, high-vibration, and radiation-exposed environments typical of defense and space applications.
How does the undershoot-protection circuitry in the 5962-9075201MRA improve system robustness?
The undershoot-protection circuitry in the 5962-9075201MRA limits negative voltage excursions on B-port outputs to ≥−0.5 V during fast edge transitions, preventing damage to downstream TTL or CMOS receivers and avoiding false triggering in noise-prone military bus environments. This feature is intrinsic to the BiCMOS output stage and requires no external components.
