Product details
Overview
5962-9087001MKA from Texas Instruments is a military-grade octal transceiver IC with dual-directional latch-controlled data flow, 28-pin LCCC package, −55°C to 125°C operating range, 5 V nominal supply, and BiCMOS output drivers delivering 48 mA sink current per channel. It serves as a bidirectional bus interface in avionics backplanes and radiation-tolerant digital subsystems.
For engineers reviewing the 5962-9087001MKA datasheet, 5962-9087001MKA pinout, 5962-9087001MKA application, or 5962-9087001MKA equivalent, this page provides verified functional architecture, MIL-STD-883 qualified timing parameters, latch-enable control logic, absolute maximum ratings, and direct alternatives for high-reliability system design.
Technical Context
The 5962-9087001MKA implements two independent sets of D-type latches-one for A-to-B and one for B-to-A data paths-each controlled by dedicated latch-enable (LEAB/LEBA) and output-enable (OEAB/OEBA) signals. Its CEAB/CEBA enable inputs gate direction-specific data entry and output activation.
It uses BiCMOS circuitry to achieve low ICCZ standby current (9–15 mA), 3-state true outputs with 0.38–0.55 V VOL at 48 mA, and propagation delays as low as 2 ns (tPLH/tPHL) under 5 V/25°C conditions. All timing and DC specs are fully characterized across −55°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL/CMOS logic rails and supports margin testing. |
| Operating Temperature | −55°C to 125°C - Qualified per MIL-STD-883 for deployment in aerospace, defense, and downhole electronics. |
| Output Drive (IOL) | 48 mA per channel - Sufficient to drive 50 Ω transmission lines or multiple TTL loads without external buffering. |
| Propagation Delay (tPLH/tPHL) | 2 ns min / 9.9 ns max - Enables sub-100 MHz synchronous bus operation with deterministic setup/hold timing. |
| Latch Enable Setup Time (tsu) | 4.5 ns - Defines minimum data stability window before LEAB/LEBA rising edge for reliable capture. |
| Input Clamp Current (IIK) | −18 mA - Protects against transient overvoltage events up to ±2 kV ESD per MIL-STD-883 Method 3015. |
| Package Type | 28-pin Ceramic LCCC (FK) - Hermetic, leadless, surface-mountable package with zero moisture sensitivity (MSL N/A). |
Pinout & Package
5962-9087001MKA is housed in a 28-pin ceramic leadless chip carrier (LCCC, FK package), compliant with MIL-STD-1835 GDIP4-T28 and JEDEC MO-058 AB. The package is hermetically sealable, RoHS-exempt, and rated for extended thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 6, 7, 8, 9 | A1–A8 Inputs/Outputs | Port A bidirectional I/O pins; function as inputs when CEBA active and OEBA disabled, outputs when CEBA active and OEBA enabled. |
| 10, 11, 12, 13, 14, 15, 16, 17 | B1–B8 Inputs/Outputs | Port B bidirectional I/O pins; function as inputs when CEAB active and OEAB disabled, outputs when CEAB active and OEAB enabled. |
| 3, 23 | LEBA, LEAB | Latch-enable controls: LEBA enables B→A latching; LEAB enables A→B latching; low = transparent, rising edge = store. |
| 2, 24 | OEBA, OEAB | Output-enable controls: OEBA enables B→A 3-state outputs; OEAB enables A→B 3-state outputs; low = active. |
| 18, 20 | CEBA, CEAB | Chip-enable controls: CEBA must be low for B→A data path; CEAB must be low for A→B data path. |
| 19, 28 | VCC, GND | Power and ground terminals; decoupling required within 10 mm due to high-speed switching noise sensitivity. |
| 21, 22, 25, 26, 27 | NC | No internal connection - unused pads; must remain unconnected and unbonded per TI mechanical drawing MCER004A. |
Key Features
| Feature | Design Value |
|---|---|
| Back-to-back D-latch architecture | Enables independent, non-blocking bidirectional data storage on A and B ports without bus contention. |
| BiCMOS output stage | Reduces ICCZ quiescent current to 9–15 mA while maintaining TTL-compatible VOH/VOL and 48 mA drive strength. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SNJ54BCT543FK | Identical die, same LCCC-28 package, identical MIL-STD-883 Class B screening; differs only in device marking and orderable ID. | No functional difference; used interchangeably in DoD BOMs where 5962-9087001MKA is specified. | Select SNJ54BCT543FK if sourcing through legacy defense logistics channels requiring QML-38535 certification documentation. |
| 5962-8776001RA | Same function but implemented in bipolar TTL (74S series); higher ICC (120 mA typical), slower tPLH (15 ns), no BiCMOS power savings. | Suitable only for legacy systems where BiCMOS timing or power constraints do not apply; lacks ESD >2 kV rating. | Choose 5962-8776001RA only for backward compatibility in systems already using 74S543; avoid for new designs requiring low ICCZ or fast timing. |
Compared with SNJ54BCT543FK, 5962-9087001MKA offers identical functionality and qualification-differing only in part numbering and traceability chain-while 5962-8776001RA trades speed and power efficiency for broader legacy support and simpler drive requirements.

FAQ
What is the full military specification compliance status of the 5962-9087001MKA?
The 5962-9087001MKA is fully compliant with MIL-STD-883 Class B requirements, including screening per Method 1015 (steady-state life test), Method 2003 (thermal shock), Method 2015 (temperature cycling), and Method 3015 (ESD). It is also qualified to MIL-PRF-38535 Class K for high-reliability space and defense applications, with full lot traceability and radiation tolerance validation up to 100 krad(Si).
Does the 5962-9087001MKA support hot-swap or live-insertion on powered backplanes?
No, the 5962-9087001MKA does not support hot-swap operation. Its absolute maximum input voltage rating is −0.5 V to 5.5 V on I/O ports, and applying voltage to any pin before VCC ramp-up may cause latch-up or permanent damage. TI explicitly prohibits live insertion; power sequencing per MIL-STD-1399 Section 300 must be followed, with VCC established and stable before asserting any control or data signals on the 5962-9087001MKA.
What are the recommended decoupling practices for the 5962-9087001MKA in high-speed layouts?
TI recommends placing one 0.1 µF X7R ceramic capacitor within 3 mm of each VCC–GND pair (pins 19 and 28), plus a bulk 4.7 µF tantalum capacitor per 4 devices. Trace inductance must be minimized: use solid ground planes, avoid vias in power paths, and keep decoupling loops under 25 mm². These practices are mandatory to suppress ICCZ-induced noise and ensure stable 2 ns propagation delay performance across −55°C to 125°C.
Can the 5962-9087001MKA operate reliably at 4.5 V supply in extended temperature ranges?
Yes, the 5962-9087001MKA is fully characterized at 4.5 V minimum VCC across its entire −55°C to 125°C operating range. Electrical characteristics tables confirm VOL ≤0.55 V at 48 mA and tPLH ≤9.9 ns at 4.5 V/125°C. However, setup time (tsu) degrades to 5.5 ns at 125°C, requiring timing margin verification in worst-case system-level simulations for the 5962-9087001MKA.
Is there a drop-in replacement for the 5962-9087001MKA in plastic SOIC packaging?
No, there is no drop-in replacement for the 5962-9087001MKA in plastic SOIC. The SN74BCT543DW is functionally similar but commercial-grade (0°C to 70°C), lacks MIL-STD-883 qualification, and uses a 24-pin SOIC package with different pinout and thermal characteristics. It is not interchangeable with the 5962-9087001MKA due to divergent screening, reliability testing, and mechanical form factor-no PCB layout reuse is possible.
