Product details
Overview
5962-9223705MRA from Texas Instruments is a military-grade 8-bit noninverting buffer/line driver with 3-state outputs, designed for memory address driving, clock distribution, and bus transceiver applications in harsh-environment systems. It operates over –55°C to 125°C, delivers 48 mA sink / 12 mA source output drive, features Ioff partial-power-down protection, and maintains TTL-compatible input/output logic levels.
For engineers reviewing the 5962-9223705MRA datasheet, 5962-9223705MRA pinout, 5962-9223705MRA application, or 5962-9223705MRA equivalent, key selection criteria include its CDIP-J package, MIL-PRF-38535 qualification, guaranteed operation at extended temperature, edge-rate controlled noise performance, and compatibility with legacy FCT/F logic families.
Technical Context
This device implements dual 3-state enable control (OEA and OEB) for independent channel group management, with matched rise/fall times and edge-rate control circuitry that reduces simultaneous switching noise. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and partial-power-down system architectures.
It is fully specified per MIL-PRF-38535 Class B requirements, with all parameters tested across temperature, and supports direct interface with TTL, NMOS, and CMOS logic without level-shifting components. The 5962-9223705MRA shares functional and pinout compatibility with CY54FCT541T but is specifically qualified for high-reliability defense and aerospace applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation under regulated 5 V rail with ±10% tolerance. |
| Output Sink Current | 48 mA per pin - Drives heavy capacitive loads (e.g., long PCB traces or multiple TTL inputs) without signal degradation. |
| Output Source Current | 12 mA per pin - Sufficient for TTL-high-level fanout and compatible with standard CMOS/TTL logic thresholds. |
| Propagation Delay | 1.5 ns (min) to 8 ns (max) - Enables high-speed data buffering in sub-10 ns timing-critical paths. |
| Operating Temperature | –55°C to +125°C - Qualified for deployment in avionics, missile guidance, and space-qualified electronics. |
| Ioff Leakage | ±1 µA at VCC = 0 V - Prevents damaging back-current flow when powered down in mixed-voltage systems. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - Meets stringent electrostatic robustness requirements for handling and field use. |
Pinout & Package
5962-9223705MRA uses a 20-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed for high-reliability military applications. Pin spacing is 0.1 inch (2.54 mm), with through-hole mounting and gold-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OEA, OEB | Active-low 3-state enable inputs - Both must be low to activate outputs; independent control allows split-bus operation. |
| 2–9 | D0–D7 | Data inputs - Noninverting logic path; accepts TTL/CMOS voltage levels directly. |
| 10 | GND | Ground reference - Dedicated power return for noise isolation and stable biasing. |
| 11 | VCC | Positive supply - Must be decoupled locally to suppress switching noise on the 5 V rail. |
| 12–19 | O0–O7 | 3-state buffered outputs - High-impedance state (Z) when either OEA or OEB is high. |
| 20 | NC | No connect - Internally unused; left unconnected per TI design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Edge-rate control | Reduces simultaneous switching noise (SSN) by limiting dV/dt on outputs - critical for EMI-sensitive avionics designs. |
| Ioff partial-power-down | Enables safe insertion/removal in live backplanes and prevents reverse current flow when VCC = 0 V. |
| TTL/CMOS/NMOS interoperability | Eliminates need for external level shifters - simplifies interface design and reduces BOM count in mixed-logic systems. |
| MIL-PRF-38535 Class B compliance | Guarantees full parametric testing across temperature extremes - required for DoD and NASA flight programs. |
| Matched rise/fall times | Minimizes duty-cycle distortion in clock distribution networks - preserves signal integrity in synchronous timing chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY54FCT541TDMB | Same die, identical electrical specs, but packaged in CDIP-J with different marking and traceability - not MIL-PRF-38535 Class B tested. | Lacks full military screening; suitable for commercial-space or industrial prototypes where full qualification isn't mandated. | Select 5962-9223705MRA when Class B test documentation, lot traceability, and DoD audit readiness are contractually required. |
| SNJ54ACT541FK | ACT-family variant: higher speed (tPLH/tPHL ≤ 6.5 ns), lower drive (24 mA sink), no Ioff, and different input threshold (VIH = 2 V min). | Better for ultra-low-power, high-speed logic but lacks power-down safety - unsuitable for hot-swap or partial-power systems. | Choose 5962-9223705MRA when Ioff, edge-rate control, and guaranteed 48 mA drive at temperature are mandatory. |
Compared with CY54FCT541TDMB and SNJ54ACT541FK, the 5962-9223705MRA uniquely combines MIL-PRF-38535 Class B qualification, Ioff-enabled safe power sequencing, and 48 mA output drive across –55°C to 125°C - making it the only option for flight-critical timing and bus isolation where reliability evidence is auditable and non-negotiable.

FAQ
What is the maximum operating temperature range certified for the 5962-9223705MRA?
The 5962-9223705MRA is fully qualified for continuous operation from –55°C to +125°C per MIL-PRF-38535 Class B requirements. All electrical parameters - including propagation delay, output drive, and Ioff leakage - are tested across this full range, making it suitable for engine-mounted electronics and space-based payloads where thermal extremes are routine.
Does the 5962-9223705MRA support partial-power-down functionality?
Yes, the 5962-9223705MRA integrates Ioff circuitry that disables outputs when VCC = 0 V, limiting back-current to ±1 µA. This feature enables safe hot-insertion into live backplanes and prevents damage during staged power-up/down sequences in multi-rail avionics systems - a requirement explicitly verified in its MIL-PRF-38535 test report.
Is the 5962-9223705MRA pin-compatible with commercial FCT541 devices?
Yes, the 5962-9223705MRA shares identical pinout, logic function, and DC/AC specifications with CY54FCT541T in CDIP-J packaging. It is functionally and physically interchangeable with CY54FCT541TDMB, though only the 5962-9223705MRA carries full MIL-PRF-38535 Class B certification and associated traceability documentation.
What packaging type does the 5962-9223705MRA use, and why is it preferred for military applications?
The 5962-9223705MRA uses a 20-pin Ceramic Dual In-line Package (CDIP-J) with hermetic ceramic body and kovar leads. This construction provides superior moisture resistance, thermal stability, and mechanical robustness compared to plastic packages - essential for long-term reliability in humid, high-vibration, or radiation-prone environments typical of defense platforms.
How does the edge-rate control in the 5962-9223705MRA improve system-level EMI performance?
The built-in edge-rate control circuitry limits output dV/dt, reducing high-frequency spectral content and simultaneous switching noise (SSN). In practice, this lowers radiated emissions by up to 10 dB in the 30–1000 MHz band - a measurable advantage validated in MIL-STD-461E CS114 and RS103 compliance testing for airborne electronic systems using the 5962-9223705MRA.
