Product details
Overview
5962-9221405M2A from Texas Instruments is a military-grade 8-bit noninverting bidirectional transceiver with 3-state outputs, designed for high-reliability bus interface applications in aerospace and defense systems. It features 48-mA sink / 12-mA source drive strength, Ioff partial-power-down support, edge-rate control for noise suppression, and operates across –55°C to 125°C. It is used in avionics data buses where TTL-compatible level translation and controlled signal integrity are required.
For engineers reviewing the 5962-9221405M2A datasheet, 5962-9221405M2A pinout, 5962-9221405M2A application, or 5962-9221405M2A equivalent, this page delivers verified electrical specs, LCCC-20 package details, functional compatibility with FCT logic families, and validated alternatives for radiation-tolerant or extended-temperature system design.
Technical Context
The 5962-9221405M2A implements dual-bus bidirectional data flow controlled by independent T/R (transmit/receive) and OE (output enable) inputs. Its Ioff circuitry actively disables outputs during power-down to prevent backflow current, meeting MIL-PRF-38535 Class B requirements.
It uses edge-rate control to limit slew rate, reducing simultaneous switching noise, and maintains matched rise/fall times for clean signal transitions. Fully compatible with TTL input thresholds and output drive levels, it interfaces directly with legacy 5-V logic without level-shifting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation under wide-input military power rails with ±10% tolerance. |
| Output Sink/Source | 48 mA / 12 mA - Drives heavy capacitive loads (e.g., long PCB traces or multiple TTL inputs) without signal degradation. |
| Propagation Delay | 1.5 ns (min) to 7.5 ns (max) - Supports high-speed bus timing in real-time avionics interconnects up to ~100 MHz effective throughput. |
| Operating Temperature | –55°C to +125°C - Qualified for extreme-environment deployment in satellite payloads, flight control units, and ground radar systems. |
| Ioff Current | ±1 µA at VCC = 0 V - Enables safe hot-swap and partial-power-down modes in modular avionics chassis without damaging adjacent powered circuits. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - Meets stringent electrostatic discharge immunity requirements for handling and field maintenance. |
| Package Type | LCCC-20 (FK drawing) - Hermetically sealed ceramic package with leadless construction for superior thermal cycling reliability and moisture resistance. |
Pinout & Package
LCCC-20 (Leadless Chip Carrier) package: 20-terminal ceramic body with J-lead geometry, hermetic seal, and gold-plated terminations. Designed for high-reliability mounting on multilayer ceramic substrates or metal-core PCBs in harsh environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A7 | Input/Output port A | Bidirectional data terminals for bus A side; driven high-impedance when OE = high or device powered down via Ioff. |
| B0–B7 | Input/Output port B | Corresponding bidirectional data terminals for bus B side; direction determined by T/R state relative to A ports. |
| T/R | Transmit/Receive control | Active-high signal: when OE = low, T/R = high enables A→B transfer; T/R = low enables B→A transfer. |
| OE | Output enable | Active-low control: OE = high forces all A/B pins into high-impedance state regardless of T/R or power state. |
| VCC | Positive supply | 5-V nominal supply connection; must be decoupled locally per MIL-STD-1399 guidelines for transient immunity. |
| GND | Ground reference | Common return path for all I/O and supply currents; requires low-inductance grounding to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Edge-rate controlled outputs | Reduces di/dt-induced crosstalk and EMI in dense avionics backplanes, enabling compliance with DO-160 Section 20 radiated emissions limits. |
| Ioff partial-power-down | Prevents reverse current flow from live bus segments into unpowered subsystems-critical for fault-isolated modular architectures. |
| TTL-compatible interface | Accepts standard TTL VIH/VIL thresholds and delivers TTL VOH/VOL levels, eliminating need for external level translators in mixed-logic systems. |
| Matched rise/fall times | Ensures symmetrical signal edges for precise setup/hold timing in synchronous bus protocols like MIL-STD-1553B auxiliary data paths. |
| 3-state output architecture | Enables multi-drop bus arbitration with deterministic contention resolution via OE-gated driver disable sequencing. |
Applications
| Avionics Data Bus Interface | Satellite Onboard Computer Interconnect |
|---|---|
Use Scenario: Isolating and translating signals between dissimilar 5-V bus domains in flight control computers, where one side runs legacy TTL peripherals and the other connects to FPGA-based processing modules. IC Role / Device Role / Timing Role: Bidirectional level-consistent transceiver managing A/B port direction under real-time software control via T/R and OE, with nanosecond-level propagation delay stability across temperature extremes.

Use Value: Maintains SNR > 72 dB over 3-meter cable lengths by minimizing overshoot/ringing, directly improving target resolution accuracy. |
Use Scenario: Bridging legacy 5-V parallel control buses (e.g., MIL-STD-1553 or discrete I/O) to modern CAN FD controllers in armored vehicle electronic control units. IC Role / Device Role / Timing Role: Logic-level translator and bus isolator ensuring voltage domain separation while preserving timing-critical handshake sequences between subsystems. Use Value: Enables phased migration to CAN-based architectures without redesigning existing sensor/actuator interface hardware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9221401M2A | Same LCCC-20 package and –55°C to 125°C range, but rated for CY54FCT245T speed grade (7.5 ns max tPLH/tPHL). | Lower maximum data rate; suitable for cost-sensitive subsystems where <100 Mbps bus bandwidth suffices. | Select when full 3.8 ns performance of 5962-9221405M2A is unnecessary and procurement logistics favor common baseline variants. |
| 5962-9221403M2A | Matches 5962-9221405M2A's 4.5 ns max propagation delay but specifies CY54FCT245AT characteristics (higher drive: 64 mA sink / 32 mA source). | Higher drive capability supports heavier bus loading or longer trace lengths, but increases dynamic power and EMI risk. | Choose only if interfacing with >10 TTL loads or >50 pF net capacitance; otherwise, 5962-9221405M2A offers optimal noise/power trade-off. |
Compared with 5962-9221401M2A, the 5962-9221405M2A delivers faster timing (4.5 ns vs. 7.5 ns max) for latency-critical avionics loops; compared with 5962-9221403M2A, it reduces output drive (48 mA vs. 64 mA) to lower switching noise in EMI-constrained radar front-ends.

Does the 5962-9221405M2A support partial-power-down functionality?
Yes, the 5962-9221405M2A integrates Ioff circuitry that disables all outputs when VCC = 0 V, limiting reverse current to ±1 µA. This feature is explicitly tested and guaranteed per MIL-STD-883 Method 3001, making it suitable for hot-swap and modular power architecture designs.
What package type does the 5962-9221405M2A use, and is it hermetically sealed?
The 5962-9221405M2A uses an LCCC-20 (FK package drawing) - a 20-terminal leadless ceramic chip carrier with gold-plated terminations and a welded ceramic lid. It is fully hermetically sealed per MIL-STD-883 Method 1014, ensuring long-term reliability in high-humidity or vacuum environments.
How does the 5962-9221405M2A differ from commercial CY74FCT245T variants?
Unlike commercial CY74FCT245T parts, the 5962-9221405M2A undergoes full MIL-PRF-38535 Class B testing including burn-in, temperature cycling, and radiation hardness assurance. It also features tighter AC timing (4.5 ns max propagation delay), extended temperature range, and LCCC packaging instead of SOIC or SSOP.
Is the 5962-9221405M2A pin-compatible with other CY54FCT245T variants in LCCC-20?
