Product details
Overview
5962-8408501VSA from Texas Instruments is a military-grade octal bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between A and B buses in harsh-environment systems. It operates from 2 V to 6 V, delivers ±6 mA output drive at 5 V, exhibits typical propagation delay of 12 ns (VCC = 4.5 V, CL = 50 pF), and supports –55°C to +125°C operation in CFP packaging.
For engineers reviewing the 5962-8408501VSA datasheet, 5962-8408501VSA pinout, 5962-8408501VSA application, or 5962-8408501VSA equivalent, key selection criteria include its MIL-PRF-38535 qualification, 20-pin CFP (W) hermetic package, DIR/OE dual-control logic, high-impedance isolation capability, and compatibility with LSTTL loads up to 15 units.
Technical Context
The 5962-8408501VSA implements CMOS-based bidirectional bus interface logic with independent direction (DIR) and output-enable (OE) controls. Its functional modes-A-to-B transmission (DIR = H), B-to-A transmission (DIR = L), and full 3-state isolation (OE = H)-are defined in the device's truth table and require no external clocking.
It features low power consumption (ICC ≤ 80 µA max), input clamp current rating of ±20 mA, and ESD robustness per MIL-STD-883 (HBM ≥ ±3000 V). Thermal resistance RθJA is 77.0°C/W in SOIC-equivalent form, though actual CFP (W) package performance differs per mechanical data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - Enables interoperability across 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | 12 ns typical at VCC = 4.5 V, CL = 50 pF - Supports high-speed bus handshaking in real-time control systems. |
| Output Drive Strength | ±6 mA at VCC = 5 V - Sufficient to directly drive 15 LSTTL loads or terminate short PCB traces. |
| Operating Temperature | –55°C to +125°C - Qualified for extended-range military avionics, ground vehicle ECUs, and space-qualified subsystems. |
| Input Leakage Current | ±1 µA max - Minimizes static loading on upstream drivers and preserves signal integrity in low-power standby modes. |
| 3-State Enable/Disable Time | ten = 26 ns, tdis = 50 ns (VCC = 4.5 V) - Ensures clean bus arbitration with minimal contention window during direction switching. |
Pinout & Package
5962-8408501VSA is housed in a 20-pin Ceramic Flatpack (CFP) package (drawing W), measuring 13.97 mm × 13.97 mm × 4.57 mm, with side-brazed leads and hermetic sealing for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DIR) | Direction Control Input | Determines data flow direction: HIGH enables A→B, LOW enables B→A; must be stable before OE activation. |
| 2–9 (A1–A8) | Port A I/O Terminals | Bidirectional data lines tied to one bus segment; high-impedance when OE = HIGH or during power-up if OE is not pulled. |
| 10 (GND) | Ground Reference | Primary return path for all internal logic and output currents; requires low-inductance connection to system ground plane. |
| 11–18 (B1–B8) | Port B I/O Terminals | Bidirectional data lines tied to second bus segment; electrically isolated from A-side when OE = HIGH. |
| 19 (OE) | Output Enable Input | Active-LOW control: drives all A/B outputs into high-impedance state when HIGH; must be pulled to VCC via resistor during power sequencing. |
| 20 (VCC) | Power Supply | Single supply input supporting 2–6 V; requires local 0.1 µF ceramic bypass capacitor placed within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | 2 V to 6 V operation allows direct interfacing with mixed-voltage systems (e.g., 3.3 V microcontrollers driving 5 V peripherals). |
| High-Current 3-State Outputs | ±6 mA drive at 5 V ensures reliable signal integrity across backplanes and long traces without external buffers. |
| Low Power Consumption | 80 µA max ICC enables use in battery-backed or thermally constrained military modules where quiescent power matters. |
| MIL-PRF-38535 Compliance | Qualified per QML Class V standards including screening, burn-in, and lot acceptance testing for mission-critical deployment. |
| ESD Robustness | ±3000 V HBM rating reduces risk of field failure during handling or in electrically noisy vehicular environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8408501VRA | Same die, CDIP (J) package instead of CFP (W); larger footprint (24.33 mm × 6.35 mm), non-hermetic plastic body. | Suitable for less demanding environmental conditions; lower cost but reduced thermal conductivity and moisture resistance. | Select 5962-8408501VRA only when board space permits larger package and hermeticity is not required. |
| JM38510/65503BSA | Identical electrical specs and CFP (W) package; differs only in marking format and lot traceability documentation per MIL-PRF-38535 Rev G. | No functional difference; used interchangeably in DoD procurement where specific drawing revision compliance is mandated. | Choose JM38510/65503BSA when contract requires Rev G compliance or legacy BOM alignment. |
Compared with 5962-8408501VSA, 5962-8408501VRA trades hermetic reliability for lower cost and easier assembly, while JM38510/65503BSA offers identical performance with alternate certification documentation-neither is pin-compatible with commercial SN74HC245 variants due to military-specific packaging and screening.

FAQ
What is the operating temperature range of the 5962-8408501VSA?
The 5962-8408501VSA is rated for operation from –55°C to +125°C, fully qualified per MIL-PRF-38535 Class V screening requirements. This range is validated through temperature cycling, steady-state life testing, and parametric verification across extremes-making it suitable for engine bay, avionics bay, and space-qualified subsystem deployments where commercial-grade HC devices would fail.
Does the 5962-8408501VSA support 3.3 V logic levels?
Yes, the 5962-8408501VSA supports 3.3 V logic levels as part of its 2 V to 6 V operating range. At VCC = 3.3 V, VIH is 2.31 V (70% of VCC) and VIL is 0.99 V (30% of VCC), ensuring reliable interfacing with standard 3.3 V CMOS and TTL-compatible outputs without level translation.
How does the DIR pin function in the 5962-8408501VSA?
The DIR pin on the 5962-8408501VSA determines data flow direction: when DIR = HIGH, data passes from Port A to Port B; when DIR = LOW, data flows from Port B to Port A. This control is asynchronous and independent of OE-direction changes take effect immediately upon DIR transition, provided OE is active (LOW).
What is the recommended power supply decoupling for the 5962-8408501VSA?
Texas Instruments recommends a 0.1 µF ceramic capacitor placed within 5 mm of the VCC pin (Pin 20) and GND (Pin 10) for the 5962-8408501VSA. For systems with multiple 5962-8408501VSA devices, add a bulk 1 µF–10 µF tantalum or ceramic capacitor near the power entry point to suppress low-frequency ripple.
Is the 5962-8408501VSA pin-compatible with commercial SN74HC245 variants?
No, the 5962-8408501VSA is not pin-compatible with commercial SN74HC245 variants. While both share identical logic functionality and 20-pin I/O assignment, the 5962-8408501VSA uses a CFP (W) ceramic flatpack package with different lead pitch, body dimensions, and solder pad layout than SOIC, PDIP, or TSSOP packages used by SN74HC245 series.
