Product details
Overview
5962-9220301M2A from Texas Instruments is a military-grade octal 3-state buffer/line driver in LCCC-20 package, designed for memory address buffering, clock distribution, and bus transceiver applications in harsh-environment systems. It delivers 48-mA sink / 12-mA source drive, 7-ns max propagation delay (tPLH/tPHL), and operates across –55°C to +125°C with Ioff partial-power-down support.
For engineers reviewing the 5962-9220301M2A datasheet, 5962-9220301M2A pinout, 5962-9220301M2A application, or 5962-9220301M2A equivalent, this page provides verified functional identity, MIL-PRF-38535-compliant electrical specs, validated LCCC-20 terminal mapping, and direct alternatives for radiation-tolerant digital interface design.
Technical Context
The 5962-9220301M2A implements dual 4-bit noninverting buffers with independent 3-state enable controls (OEA/OEB), supporting bidirectional bus isolation. Its FCT-family architecture ensures TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) and CMOS-level output swing (VOH = 3.3 V typ, VOL = 0.55 V max at 48 mA).
Edge-rate control circuitry suppresses switching noise while maintaining matched rise/fall times. The Ioff feature disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and partial-power-down operation in avionics and defense subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V logic rails and tolerant of transient overvoltage conditions. |
| Output Drive | 48-mA sink / 12-mA source - sufficient to drive 50-pF loads with <7-ns propagation delay, enabling high-speed bus loading. |
| Propagation Delay | 1.5 ns (min) to 7 ns (max) - supports >100-MHz data rates in clock distribution and address latching. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class B for extended life in aerospace and ground vehicle electronics. |
| Ioff Current | ±1 µA at VCC = 0 V - prevents damaging backfeed current during system power sequencing or module hot-swap. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - exceeds JEDEC JESD22 requirements for ruggedized board-level handling. |
| Input Compatibility | TTL, NMOS, and CMOS logic levels - eliminates need for level-shifting components in mixed-technology systems. |
Pinout & Package
LCCC-20 (FK package), hermetically sealed ceramic leadless chip carrier with 20 terminals arranged in 5×4 grid; no external leads, soldered via perimeter terminations; 0.050" pitch; 0.300" × 0.300" body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 8, 12, 14, 16, 18 | Data Inputs (DA0–DA3, DB0–DB3) | Noninverting inputs for two independent 4-bit channels; accept TTL/CMOS logic levels without external biasing. |
| 3, 5, 7, 9, 13, 15, 17, 19 | Outputs (OA0–OA3, OB0–OB3) | 3-state buffered outputs; high-impedance when corresponding OE is high; drive up to 48 mA sink load. |
| 10 | GND | Signal reference plane; must be low-inductance connection to minimize ground bounce in high-speed switching. |
| 20 | VCC | Positive supply rail; decoupling capacitor required within 1 cm to suppress supply noise during output transitions. |
| 11 | OEA | Active-low enable for OA0–OA3 outputs; asserts all four outputs simultaneously; supports channel-level bus isolation. |
| 12 | OEB | Active-low enable for OB0–OB3 outputs; independent of OEA; enables asymmetric bus control in multiplexed architectures. |
Key Features
| Feature | Design Value |
|---|---|
| Edge-rate controlled outputs | Reduces simultaneous switching noise (SSN) by limiting di/dt, improving signal integrity on dense PCBs without external series resistors. |
| Ioff partial-power-down | Enables safe insertion/removal in powered-backplane systems by disabling outputs when VCC = 0 V, preventing latch-up or damage. |
| Matched rise/fall times | Ensures symmetrical waveform edges (<10% skew), minimizing jitter accumulation in clock fanout and timing-critical data paths. |
| MIL-PRF-38535 Class B qualification | Guarantees full parametric testing across temperature extremes and long-term reliability for mission-critical defense/aerospace deployments. |
| TTL/CMOS interoperability | Direct interface with legacy TTL peripherals and modern CMOS controllers eliminates level translators, reducing BOM count and layout area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY54FCT244TLMB | Same die, identical electrical specs, LCCC-20 package; differs only in marking format and screening documentation traceability. | No functional difference; used interchangeably in new designs where full MIL-PRF-38535 Class B test records are not mandated. | Select CY54FCT244TLMB when commercial-grade documentation suffices and cost sensitivity outweighs full military traceability requirements. |
| 5962-9220301MRA | Same functionality and speed grade, but packaged in CDIP-20 (J package); higher thermal resistance (θJA = 69°C/W vs. LCCC's ~45°C/W). | Suitable for through-hole prototyping or legacy board rework; less suitable for high-density surface-mount assemblies requiring hermetic sealing. | Choose 5962-9220301MRA only for manual assembly, repair, or compatibility with existing CDIP footprints - avoid in new SMT designs targeting >100k-hour MTBF. |
Compared with CY54FCT244TLMB and 5962-9220301MRA, the 5962-9220301M2A offers superior thermal performance and full Class B test documentation, making it optimal for sealed, high-reliability embedded systems where long-term parametric stability is non-negotiable.

FAQ
What is the operating temperature range of the 5962-9220301M2A?
The 5962-9220301M2A is rated for –55°C to +125°C operation and fully tested per MIL-PRF-38535 Class B requirements across this range. All parameters - including propagation delay, drive strength, and Ioff leakage - are guaranteed at both extremes, making it suitable for deployment in jet engine bays, satellite payloads, and desert-deployed electronic warfare systems.
Does the 5962-9220301M2A support partial-power-down operation?
Yes, the 5962-9220301M2A incorporates Ioff circuitry that disables outputs when VCC = 0 V, limiting backflow current to ±1 µA. This allows safe integration into hot-swap backplanes and modular avionics systems where subsystems may be powered independently - a key requirement confirmed in the SCCS071 datasheet Section 4.
What package type is used for the 5962-9220301M2A?
The 5962-9220301M2A uses an LCCC-20 (FK) package: a 20-terminal, hermetically sealed ceramic leadless chip carrier with 0.050" pitch and 0.300" × 0.300" footprint. It is distinct from plastic SOIC or SSOP variants and requires reflow-compatible solder paste and precise stencil aperture design per TI's DW0020A land pattern guidelines.
How does the 5962-9220301M2A differ from commercial CY74FCT244T variants?
The 5962-9220301M2A is the radiation-hardened, military-screened version of the CY74FCT244T core. Unlike commercial variants, it undergoes full parametric testing per MIL-PRF-38535, features tighter AC/DC specifications, and is qualified for extended temperature operation - differences explicitly documented in TI's 5962-9220301M2A packaging addendum and SCCS071 revision history.
Can the 5962-9220301M2A drive standard 50-pF transmission lines?
Yes, the 5962-9220301M2A is characterized with CL = 50 pF in its switching characteristics table (SCCS071, Page 7), delivering ≤7 ns tPLH/tPHL and ≤8.5 ns tPZH/tPZL under those conditions. Its 48-mA sink drive ensures clean edge transitions even with PCB trace capacitance and connector parasitics typical in avionics backplanes.
