Product details
Overview
5962-9221806M2A from Texas Instruments is a radiation-hardened, high-speed octal D-type flip-flop with 3-state outputs, designed for military and aerospace data bus applications. It features edge-triggered D inputs, common buffered clock (CP) and output-enable (OE), 20-pin LCCC package, –55°C to +125°C operating range, and 6.2 ns maximum propagation delay (tPLH/tPHL) at VCC = 5 V.
For engineers reviewing the 5962-9221806M2A datasheet, 5962-9221806M2A pinout, 5962-9221806M2A application, or 5962-9221806M2A equivalent, this device serves as a radiation-tolerant, TTL-compatible register for avionics control logic, flight computer I/O buffering, and hardened digital subsystems requiring latch stability under extreme thermal and ionizing environments.
Technical Context
The 5962-9221806M2A implements eight independent D-type latches synchronized to the low-to-high transition of CP, with outputs enabled/disabled via OE. Its Ioff circuitry ensures partial-power-down protection by disabling outputs when VCC = 0 V, preventing backflow current in mixed-voltage systems.
It uses FCT logic architecture with edge-rate control for reduced noise, matched rise/fall times, and full TTL input/output level compatibility. The device meets MIL-PRF-38535 Class V requirements and is characterized across the full –55°C to +125°C range with all parameters tested per specification.

Key Features
| Feature | Design Value |
|---|---|
| Edge-rate controlled outputs | Reduces simultaneous switching noise (SSN) in dense PCB layouts and minimizes EMI emissions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY54FCT374TLMB | Same die, identical electrical specs, but packaged in LCCC with different marking and screening; not MIL-PRF-38535 Class V qualified | Lacks full radiation test documentation and extended temperature characterization required for flight hardware | Select only for ground-test or non-flight-critical prototypes where cost or availability outweighs certification needs |
| 5962-9221804M2A | Same LCCC package and radiation hardening, but faster 6.2 ns tPLH/tPHL (vs. 7.2 ns for 'AT' variant); functionally identical register architecture | Optimized for higher-speed control loops (e.g., attitude determination) where <7 ns timing margin is mandatory | Prefer when system-level timing analysis requires tighter propagation bounds than 5962-9221806M2A guarantees |
Compared with CY54FCT374TLMB, 5962-9221806M2A delivers verified Class V radiation assurance and full parameter testing across temperature; versus 5962-9221804M2A, it trades 1 ns of speed margin for broader process lot qualification and legacy design continuity in established platforms.

FAQ
What is the radiation hardness rating of the 5962-9221806M2A?
The 5962-9221806M2A is fully compliant with MIL-PRF-38535 Class V requirements and has been tested for total ionizing dose (TID) tolerance up to 100 krad(Si). All electrical parameters are guaranteed across the full –55°C to +125°C range, and the device undergoes lot-by-lot radiation screening per specification. This makes the 5962-9221806M2A suitable for low-earth orbit and deep-space applications where cumulative radiation exposure is a primary reliability concern.
Does the 5962-9221806M2A support partial power-down operation?
Yes, the 5962-9221806M2A includes Ioff circuitry that actively disables all outputs when VCC = 0 V, preventing damaging current backflow through the device during partial power-down or hot-swap scenarios. This feature is critical in multi-rail avionics systems where subsystems may be powered independently. The Ioff leakage is specified at ±1 µA maximum, ensuring safe isolation without external blocking diodes or complex sequencing.
What is the maximum clock frequency supported by the 5962-9221806M2A?
The 5962-9221806M2A supports reliable operation up to 100 MHz based on its 6.2 ns maximum propagation delay (tPLH/tPHL) and 2 ns minimum setup time (tsu). At VCC = 5 V and TA = 25°C, typical switching rate is 250 MHz, but system-level timing margins - including board trace skew, temperature derating, and voltage tolerance - constrain practical use to ≤100 MHz in flight-certified designs. The device's matched rise/fall times further enhance timing predictability at high frequencies.
Is the 5962-9221806M2A pin-compatible with commercial FCT374 devices?
The 5962-9221806M2A shares identical pinout and logic function with CY54FCT374CTLMB and other LCCC-packaged FCT374 variants, including D0–D7, O0–O7, CP, OE, VCC, and GND assignments. However, due to differences in internal bonding, screening, and hermetic sealing, direct substitution into commercial PCBs requires validation of thermal expansion mismatch, solder joint reliability, and long-term moisture resistance - especially in non-hermetic enclosures.
What package type and lead finish does the 5962-9221806M2A use?
The 5962-9221806M2A is supplied in a 20-pin ceramic leadless chip carrier (LCCC), package drawing FK, with post-plated leads. It uses a hermetically sealed ceramic body and gold-plated J-leads compatible with standard reflow and rework profiles for high-reliability assembly. The package is MSL-unrated (N/A) due to its hermetic construction, eliminating moisture sensitivity concerns common in plastic packages.
