Product details
Overview
5962-9094001MRA from Texas Instruments is a military-grade 16-bit bus transceiver with dual output-enable control (OEAB/OEBA), BiCMOS architecture, and true data output logic. It supports bidirectional asynchronous data transfer between A and B buses, operates from −55°C to 125°C, and delivers 48 mA low-level output drive on B-port at VCC = 4.5 V - used in avionics backplane interfaces and radiation-tolerant data routing systems.
For engineers reviewing the 5962-9094001MRA datasheet, 5962-9094001MRA pinout, 5962-9094001MRA application, or 5962-9094001MRA equivalent, key selection criteria include its MIL-STD-883 qualified CDIP-20 package, dual-enable storage mode, ±2000 V ESD protection, and guaranteed switching performance under full military temperature range.
Technical Context
The 5962-9094001MRA implements a dual-bus transceiver topology with independent OEAB (A→B enable) and OEBA (B→A enable) inputs, enabling four distinct operational states: isolation, unidirectional A→B, unidirectional B→A, and simultaneous bidirectional transfer. Its BiCMOS design reduces ICCZ quiescent current to 6–11 mA while maintaining TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V).
Switching behavior is characterized across temperature: tPLH/tPHL propagation delays range from 0.5 ns to 8.3 ns (A↔B paths), with output-enable timing (tPZH/tPLZ) as fast as 0.3 ns (OEAB→B). All I/O ports tolerate −0.5 V to 5.5 V, and outputs drive up to 64 mA (B-port, SN74 variant) or 48 mA (B-port, SN54/5962 variant) under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures compatibility with standard 5-V TTL and military power rails. |
| Operating Temperature | −55°C to 125°C - fully qualified per MIL-STD-883 for aerospace and defense embedded systems. |
| B-Port IOL | 48 mA at VCC = 4.5 V - sufficient to drive multiple TTL loads without external buffering. |
| tPHL (B→A) | Max 7.6 ns at TA = 125°C - enables reliable high-speed bus arbitration in real-time control subsystems. |
| ESD Protection | >2000 V per MIL-STD-883C Method 3015 - meets ruggedized handling requirements for field-deployable hardware. |
| ICCZ Quiescent Current | 6–11 mA at VCC = 5.5 V - minimized by BiCMOS process for reduced standby power in always-on modules. |
| Input Clamp Current | −18 mA - protects against transient overvoltage on control lines during hot-swap or fault events. |
Pinout & Package
5962-9094001MRA is supplied in a hermetically sealed Ceramic Dual-In-Line Package (CDIP) with 20 leads (Package Drawing J), compliant with MIL-PRF-38535 Class K requirements. The package provides enhanced thermal stability and moisture resistance for long-term deployment in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 20 | VCC / GND | Power supply and ground reference - decoupling required within 10 mm for noise immunity. |
| 2–9, 18–11 | A1–A8 / B1–B8 | Bidirectional data terminals - electrically identical I/O ports supporting TTL voltage levels and drive strength. |
| 10 | GND | Signal ground return - tied internally to substrate; must be connected to system ground plane. |
| 19 | OEAB | Active-low A-to-B output enable - controls directionality and isolation of A→B path. |
| 12 | OEBA | Active-low B-to-A output enable - independently gates B→A data flow and enables dual-enable storage mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | Enables four discrete functional modes (isolation, A→B, B→A, simultaneous bidirectional) without external logic. |
| True data output logic | Outputs reflect exact input state - no inversion or latching unless enabled via OEAB/OEBA combination. |
| BiCMOS process technology | Reduces ICCZ by >50% vs. bipolar-only equivalents - critical for thermally constrained military chassis. |
| MIL-STD-883 qualified | Includes screening for burn-in, temperature cycling, and mechanical shock - required for DoD procurement compliance. |
| High-current B-port drive | 48 mA sink capability supports direct interfacing to legacy TTL bus loads without level-shifting or buffering. |
Applications
| Avionics Data Bus Interface | Tactical Radios Backplane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54BCT623J | Identical electrical specs and CDIP-20 package; same MIL-STD-883 screening level and temperature range. | No functional difference - differs only in TI's internal part numbering convention and traceability marking. | Select when sourcing through legacy TI military distribution channels or requiring TI's standard SNJ prefix for documentation alignment. |
| 5962-8763301VFA | Also a 16-bit BiCMOS transceiver but uses different enable logic (single OE with direction control) and has higher ICCZ (15 mA typical). | Lacks dual-enable storage mode; not suitable for applications requiring simultaneous bus hold on both sides. | Choose only if board layout already accommodates single-OE footprint and dual-enable functionality is unused in system architecture. |
Compared with 5962-9094001MRA, SNJ54BCT623J offers identical performance and qualification with minor marking differences, while 5962-8763301VFA sacrifices dual-enable flexibility and quiescent efficiency for simplified control - making it a functional alternative only in non-storage-mode use cases.

FAQ
What is the operating temperature range certified for the 5962-9094001MRA?
The 5962-9094001MRA is fully characterized and qualified for operation from −55°C to 125°C per MIL-STD-883, with all electrical parameters tested across this full military temperature range. This includes guaranteed propagation delays, output drive strength, and input threshold stability - essential for deployment in jet engine bays, satellite payload bays, and desert-deployed command posts where ambient extremes exceed commercial limits.
Does the 5962-9094001MRA support simultaneous bidirectional data transfer?
No - the 5962-9094001MRA does not support true simultaneous bidirectional transfer on the same bus pair. However, it enables controlled bidirectional operation via independent OEAB and OEBA signals: when OEAB is active, A→B data flows; when OEBA is active, B→A data flows; and when both are active, both ports enter high-impedance reinforcement mode - holding last valid states but not passing new data concurrently in both directions.
What package type is used for the 5962-9094001MRA, and is it hermetically sealed?
The 5962-9094001MRA uses a Ceramic Dual-In-Line Package (CDIP) with 20 leads (Package Drawing J), as confirmed in TI's Package Option Addendum. This package is hermetically sealed per MIL-PRF-38535 requirements, providing moisture resistance, thermal stability, and long-term reliability in vacuum, high-humidity, and thermal-cycling environments typical of aerospace and defense applications.
How does the dual-enable feature of the 5962-9094001MRA improve system-level fault tolerance?
The dual-enable (OEAB/OEBA) architecture of the 5962-9094001MRA allows precise, independent control of data flow direction and bus isolation. During fault conditions - such as bus contention or upstream failure - either enable can be deasserted to isolate one side while maintaining integrity on the other. When both are asserted, the device enters storage mode, preserving bus state without external latches - reducing component count and single-point failure risks in safety-critical C4I systems.
Is the 5962-9094001MRA RoHS-compliant, and what is its lead finish?
The 5962-9094001MRA is not RoHS-compliant; it contains lead per MIL-PRF-38535 Class K requirements and is designated as "RoHS Exempt" by Texas Instruments. Its lead finish is SnPb (tin-lead), optimized for high-reliability solder joints in military reflow and wave-solder processes. This exemption applies under EU Directive 2011/65/EU Annex III for aerospace and defense applications where reliability outweighs restriction mandates.
