Product details
Overview
5962-9221303MRA from Texas Instruments is a military-grade octal buffer/line driver with 3-state outputs, designed for memory address and clock distribution in high-reliability systems. It features 48-mA sink / 12-mA source drive, Ioff partial-power-down support, edge-rate control for noise reduction, and operates across –55°C to 125°C.
For engineers reviewing the 5962-9221303MRA datasheet, 5962-9221303MRA pinout, 5962-9221303MRA application, or 5962-9221303MRA equivalent, this page delivers verified electrical specs, CDIP-20 package details, functional compatibility with FCT logic families, and real-world use cases in avionics timing and ruggedized bus interfaces.
Technical Context
The 5962-9221303MRA implements dual 4-bit noninverting buffers with independent 3-state enable controls (OEA/OEB), supporting TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and CMOS-level output swing (VOH = 2.4 V min at 12 mA). Its Ioff circuitry ensures ≤±1 µA leakage when VCC = 0 V, enabling safe back-drive prevention during partial power-down.
It uses edge-rate controlled output drivers to limit di/dt, achieving matched rise/fall times and reducing simultaneous switching noise. The device meets MIL-PRF-38535 Class B requirements and supports direct interface with TTL, NMOS, and CMOS without external level-shifting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Enables stable operation with standard 5-V military power rails. |
| Output Sink Current | 48 mA per pin - Drives heavy capacitive loads (e.g., long PCB traces or multiple TTL inputs) without signal degradation. |
| Propagation Delay | 1.5–9 ns - Supports high-speed address/clock buffering up to ~100 MHz system timing. |
| Ioff Leakage | ±1 µA at VCC = 0 V - Prevents damaging current flow during hot-swap or staged power sequencing. |
| Operating Temperature | –55°C to +125°C - Qualified for airborne, space, and ground vehicle electronics per MIL-STD-883. |
| ESD Protection | 2000-V HBM - Sustains handling and board assembly without gate oxide damage. |
| Input Capacitance | 5 pF - Minimizes loading on upstream drivers and preserves signal integrity in fanout-critical paths. |
Pinout & Package
5962-9221303MRA is housed in a hermetically sealed 20-pin Ceramic Dual In-line Package (CDIP-J), rated for harsh environments and long-term reliability. Pin 10 is GND and Pin 11 is VCC; the package includes integrated heat-spreading capability and meets MIL-STD-1835 outline J.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OEA | Output Enable A | Active-low control for first 4-channel buffer group (OA0–OA3); enables/disables outputs simultaneously. |
| OEB | Output Enable B | Active-low control for second 4-channel buffer group (OB0–OB3); allows independent bus segment management. |
| DA0–DA3 | Data Inputs A | Noninverting inputs for OA0–OA3 outputs; accept TTL/CMOS logic levels directly. |
| DB0–DB3 | Data Inputs B | Noninverting inputs for OB0–OB3 outputs; electrically isolated from A-side for dual-bus isolation. |
| OA0–OA3 | Outputs A | 3-state noninverting buffered outputs; high-impedance state asserted when OEA = high. |
| OB0–OB3 | Outputs B | 3-state noninverting buffered outputs; high-impedance state asserted when OEB = high. |
| VCC | Power Supply | +5 V supply pin (Pin 11); requires local 0.1-µF ceramic decoupling adjacent to package. |
| GND | Ground | Signal reference (Pin 10); must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Edge-Rate Control | Slows output transitions to reduce EMI and crosstalk in dense routing environments. |
| Ioff Partial-Power-Down | Disables outputs and blocks reverse current flow when VCC is unpowered - critical for hot-swap and modular subsystems. |
| TTL-Compatible Interface | Accepts standard TTL input thresholds and drives TTL loads directly - eliminates level translators in legacy designs. |
| Matched Rise/Fall Times | Ensures symmetrical waveform edges, minimizing duty-cycle distortion in clock distribution applications. |
| MIL-PRF-38535 Qualification | Manufactured under military quality flow with 100% screening, lot traceability, and extended environmental testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY54FCT240ATDMB | Same die, identical electrical specs, CDIP-20 package, but marked per TI internal part numbering (not 5962- prefix). | No difference - fully interchangeable in form, fit, and function for new designs and replacements. | Select when sourcing through commercial TI channels; verify QPL listing if required for defense contracts. |
| 5962-9221301MRA | Same CDIP-20 package and temperature range, but configured as octal inverting buffer ('240 vs '241 logic function). | Requires logic inversion in upstream/downstream logic; not drop-in for noninverting paths. | Choose only when system-level logic design accommodates inverted data flow - no electrical rework needed, but functional verification required. |
Compared with CY54FCT240ATDMB, 5962-9221303MRA offers identical performance and military traceability, while 5962-9221301MRA provides an inverting alternative requiring signal polarity validation - both avoid redesign but differ in functional compatibility.

Does the 5962-9221303MRA support partial-power-down functionality?
Yes, the 5962-9221303MRA includes Ioff circuitry that disables all outputs and limits leakage to ±1 µA when VCC = 0 V. This feature protects downstream circuitry during staged power-up/down sequences and is fully characterized per MIL-STD-883 Method 3023.
Is the 5962-9221303MRA pin-compatible with commercial CY74FCT240T variants?
No - the 5962-9221303MRA uses a CDIP-20 (J) package, while commercial CY74FCT240T variants are offered in SOIC (DW), SSOP (DBQ), or QSOP (D) packages. Pin functions match, but physical layout, thermal characteristics, and soldering processes differ significantly.
What is the typical propagation delay of the 5962-9221303MRA at 5 V?
The 5962-9221303MRA exhibits a typical propagation delay of 1.5 ns (min) to 9 ns (max) from input to output under recommended operating conditions (VCC = 4.5–5.5 V, TA = –55°C to +125°C), as measured per Figure 1 load conditions in the SCCS017A datasheet.
Can the 5962-9221303MRA drive TTL loads directly without level-shifting components?
Yes, the 5962-9221303MRA is fully compatible with TTL input and output logic levels: it accepts VIH = 2 V and VIL = 0.8 V, and delivers VOH ≥ 2.4 V (at 12 mA) and VOL ≤ 0.55 V (at 48 mA), satisfying standard TTL voltage thresholds across its full temperature range.
