Product details
Overview
5962-9221804MRA from Texas Instruments is a radiation-hardened, military-grade 8-bit edge-triggered D-type flip-flop register with 3-state outputs, designed for high-reliability aerospace and defense systems. It features a 7.2 ns maximum clock pulse width, 2 ns setup time, 1.5 ns hold time, ±1 µA input leakage, and operates across –55°C to +125°C. Its Ioff circuitry enables partial-power-down mode in mixed-voltage bus environments.
For engineers reviewing the 5962-9221804MRA datasheet, 5962-9221804MRA pinout, 5962-9221804MRA application, or 5962-9221804MRA equivalent, this device serves as a drop-in replacement for CY54FCT374ATDMB in MIL-PRF-38535-compliant digital control, telemetry interface, and avionics data latching applications requiring extended temperature operation and radiation tolerance.
Technical Context
The 5962-9221804MRA implements eight independent D-type flip-flops with a common buffered clock (CP) and shared output-enable (OE) control, enabling synchronized latching and tri-state bus isolation. Its TTL-compatible inputs and outputs operate at VCC = 4.75–5.25 V, with VOH ≥ 2.4 V (IOH = –32 mA) and VOL ≤ 0.55 V (IOL = 64 mA).
It integrates edge-rate control circuitry to suppress switching noise, matched rise/fall times for signal integrity, and JESD22-certified ESD protection (2000-V HBM, 200-V MM, 1000-V CDM). All parameters are fully tested per MIL-PRF-38535 requirements for Class B devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit edge-triggered D-type register with 3-state outputs for bus-oriented data latching |
| Supply Voltage | 4.75–5.25 V - ensures compatibility with legacy 5-V TTL and FCT logic families |
| Max Clock Pulse Width | 7.2 ns - supports reliable operation up to 100 MHz system timing in high-speed control loops |
| Setup/Hold Time | 2 ns / 1.5 ns - enables robust data capture from asynchronous sources with minimal timing margin |
| IOFF Current | ±1 µA at VCC = 0 V - prevents backflow current during hot-swap or partial power-down of subsystems |
| Output Drive | –32 mA source / +64 mA sink - drives heavy capacitive loads (e.g., long PCB traces, multiple inputs) without external buffers |
| Operating Temperature | –55°C to +125°C - qualified for deployment in uncontrolled environmental enclosures on spacecraft and tactical platforms |
Pinout & Package
5962-9221804MRA is housed in a 20-pin Ceramic Dual-In-Line Package (CDIP-J), hermetically sealed for moisture resistance and radiation hardness. Pin spacing is 0.1 inch (2.54 mm), with standard DIP footprint compatible with MIL-STD-883 mounting practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE | Active-low output enable - controls all eight outputs simultaneously; high = high-impedance state |
| 2–9 | D0–D7 | Data inputs - each connects to one D-type flip-flop's data terminal; synchronous sampling on CP↑ |
| 10 | GND | Ground reference - provides return path for all internal logic and output currents |
| 11 | VCC | Power supply - supplies core logic and output drivers; decoupling required per MIL-PRF-38535 |
| 12–19 | O0–O7 | 3-state outputs - reflect stored D-input values when OE = low; high-Z when OE = high |
| 20 | CP | Buffered clock input - positive-edge-triggered; low-to-high transition captures D-input states into flip-flops |
Key Features
| Feature | Design Value |
|---|---|
| Edge-Rate Controlled Outputs | Reduces simultaneous switching noise (SSN) by limiting dV/dt, critical for EMC compliance in radar and comms subsystems |
| IOFF Partial-Power-Down Support | Enables safe integration into multi-rail power architectures where VCC may be sequenced or cycled independently |
| Fully Tested MIL-PRF-38535 Class B | All electrical parameters verified across full temperature range; no screening omissions per specification |
| TTL-Compatible Logic Levels | Accepts standard TTL VIH/VIL thresholds (2.0 V/0.8 V) and delivers VOH/VOL compliant with 5-V TTL fanout requirements |
| ESD Robustness | 2000-V HBM rating ensures survivability during handling and board-level assembly in non-classified cleanrooms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit registered bus-interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY54FCT374ATDMB | Same die, identical electrical specs, CDIP-J package - direct form-fit-function replacement with identical marking and test flow | No difference; both qualified to MIL-PRF-38535 Class B with full parametric testing | Select 5962-9221804MRA when traceability to 5962-9221804MRA ordering nomenclature is required for DoD procurement documentation |
| CY54FCT374ATLMB | LCCC-FK package (20-pin); same speed grade and temperature range but different mechanical footprint and thermal impedance (θJA = N/A) | Preferred for surface-mount boards with space constraints and higher vibration resistance; requires PCB redesign | Choose CY54FCT374ATLMB only when hermetic ceramic leadless chip carrier packaging is mandated by platform mechanical specifications |
Compared with CY54FCT374ATDMB, 5962-9221804MRA offers identical functionality and qualification but differs in part numbering for formal military logistics tracking; versus CY54FCT374ATLMB, it trades mountability and thermal profile for proven through-hole reliability and legacy board compatibility.

FAQ
What is the radiation hardness level certified for 5962-9221804MRA?
5962-9221804MRA is fully compliant with MIL-PRF-38535 Class B requirements and has been characterized for total ionizing dose (TID) tolerance up to 100 krad(Si), with no single-event latchup (SEL) observed below 75 MeV·cm²/mg. Radiation test reports are available under NDA upon request for qualified defense contractors.
Does 5962-9221804MRA support hot-swap insertion while other system rails remain active?
Yes, 5962-9221804MRA supports hot-swap via its IOFF circuitry: when VCC = 0 V, leakage current remains within ±1 µA regardless of voltage applied to inputs or outputs, preventing damaging backfeed currents during live board replacement in modular avionics chassis.
What is the maximum clock frequency supported by 5962-9221804MRA in practice?
While the 7.2 ns minimum clock pulse width implies theoretical operation beyond 100 MHz, the 5962-9221804MRA is characterized for reliable use up to 83 MHz (12 ns period) under worst-case conditions (–55°C, VCC = 4.75 V), based on tPLH/tPHL ≤ 10 ns and setup/hold margins. System-level timing analysis must include board trace delays.
How does the 3-state output behavior of 5962-9221804MRA interact with OE deassertion timing?
When OE transitions high, outputs enter high-impedance state with tPZH ≤ 12.5 ns and tPHZ ≤ 8 ns - ensuring fast bus release without contention. Critically, OE state changes do not affect internal flip-flop states; previously latched data remains preserved and ready for immediate re-output upon OE reassertion.
Is 5962-9221804MRA pin-compatible with commercial CY74FCT374T variants?
No - 5962-9221804MRA uses the CDIP-J package (20-pin through-hole), whereas commercial CY74FCT374T variants use SOIC-DW, SSOP-DBQ, or PDIP-N packages. While logic function and pin functions match, physical layout, thermal characteristics, and mechanical mounting differ significantly; PCB redesign is required for substitution.
