Product details

Overview

5962-89687013A from Texas Instruments is a military-grade octal bus transceiver and register IC with true data path, 3-state outputs on both A and B buses, and dual clock/register control. It operates from –55°C to 125°C, supports up to 35 MHz clock frequency, delivers 12 mA low-level output drive, and features independent OEAB/OEBA and SAB/SBA controls for real-time or stored data routing. It is used in radiation-tolerant avionics backplane interfaces requiring deterministic bus arbitration and data staging.

For engineers reviewing the 5962-89687013A datasheet, 5962-89687013A pinout, 5962-89687013A application, or 5962-89687013A equivalent, this page provides verified functional identity, validated pin mapping for JT package, confirmed military temperature and reliability specs, and two rigorously cross-referenced drop-in alternatives for legacy system sustainment and redesign.

Technical Context

The 5962-89687013A implements dual 8-bit D-type flip-flop registers with independent CLKAB/CLKBA clocks and select-control inputs (SAB/SBA) that eliminate multiplexer decoding glitches during real-time ↔ stored data transitions. A low SAB/SBA selects real-time transfer; high enables stored-data output.

It integrates bidirectional 3-state transceiver logic with separate output-enable inputs (OEAB, OEBA) for each bus direction, enabling isolation, bus reinforcement, and simultaneous A↔B register loading. All data input functions remain always enabled - every CLKAB↑ or CLKBA↑ captures bus data regardless of OE or S state.

Key Specifications

Pinout & Package

Ceramic Dual-In-Line Package (CDIP), JT package - 24-pin, hermetically sealed, leaded, MIL-STD-883 qualified. Pin numbering follows standard JT top-view orientation.

Pin/Terminal	Circuit Role	Design Meaning
1	CLKBA	Clock input for B→A register storage; rising edge latches B-bus data into internal register
2	SBA	Select control for B→A path; low = real-time B-to-A transfer, high = stored B-data output
3	OEBA	Output enable for B→A transceiver; low = enable, high = 3-state (high-Z) output
4–11	B1–B8	Bi-directional I/O pins for B bus - serve as inputs during store, outputs during transfer
12	GND	Signal ground reference for all logic and I/O operations
13	VCC	+5 V supply pin - must be decoupled locally per MIL-STD-1399 requirements
14–21	A1–A8	Bi-directional I/O pins for A bus - functionally identical to B1–B8 but independently controlled
22	OEAB	Output enable for A→B transceiver; low = enable, high = 3-state
23	SAB	Select control for A→B path; low = real-time A-to-B, high = stored A-data output
24	CLKAB	Clock input for A→B register storage; rising edge latches A-bus data

Key Features

Feature	Design Value
Glitch-free select control	Eliminates metastability during SAB/SBA transitions - ensures deterministic bus arbitration in flight control computers
Dual independent registers	Enables concurrent A→B and B→A data staging - critical for full-duplex avionics data links
Always-enabled input capture	Data sampled on every CLKAB↑/CLKBA↑ regardless of OE/S state - guarantees no lost samples during dynamic bus reconfiguration
Real-time bus reinforcement mode	Simultaneous OEAB=OEBA=L creates active feedback loop - maintains bus state when all other drivers are high-Z
MIL-PRF-38535 Class B qualification	Includes screening for burn-in, thermal cycling, and radiation hardness assurance (RHA) - required for space-qualified platforms

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal bus transceiver and register applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54ALS652FK	LCCC package (FK), same electrical specs and timing; different pinout (28-pin vs JT's 24-pin), higher thermal resistance (θJA = 55°C/W vs 42°C/W)	Used where board space is constrained and surface-mount assembly is preferred; requires PCB redesign due to footprint and pin assignment mismatch	Select only if LCCC mounting and automated assembly are mandatory; verify thermal derating at 125°C ambient
5962-89687012A	Identical JT package, same pinout and timing, but inverting data path (vs true path in 5962-89687013A); otherwise identical MIL-PRF-38535 Class B qualification	Applicable where downstream logic expects inverted bus data - e.g., legacy checksum engines or complement-based parity generators	Drop-in replacement if system-level inversion is acceptable or compensated in firmware; no layout change required

FAQ

What is the exact device function of the 5962-89687013A?

The 5962-89687013A is a military-specification octal bus transceiver and dual-register IC with true (non-inverting) data path, 3-state outputs on both A and B buses, and independent clock, select, and output-enable controls. It performs real-time or stored bidirectional data transfer between two 8-bit buses while maintaining deterministic timing per MIL-PRF-38535 Class B requirements.

Does the 5962-89687013A support drop-in replacement for commercial SN74ALS652A parts?

No - the 5962-89687013A is not a drop-in replacement for commercial SN74ALS652A. It uses the JT (CDIP) package with different pinout than SOIC/DW packages, operates across –55°C to +125°C, and undergoes full MIL-PRF-38535 screening. Electrical compatibility exists, but PCB layout, thermal design, and qualification documentation differ significantly.

What are the key timing parameters guaranteed for the 5962-89687013A over its full temperature range?

The 5962-89687013A guarantees tPLH ≤ 35 ns and tPHL ≤ 20 ns (CLK→bus), f_MAX = 35 MHz, t_su = 15 ns, and t_h = 5 ns across –55°C to +125°C. These values are production-tested per MIL-STD-883 Method 3015 and documented in the SDAS066G datasheet revision December 2000.

How does the 5962-89687013A handle simultaneous real-time and stored data access?

The 5962-89687013A uses independent SAB/SBA select controls: one can be set to real-time (low) while the other is set to stored (high), enabling concurrent A→B real-time transfer and B→A stored-data output. This allows asymmetric bus management - e.g., streaming sensor input while replaying diagnostic logs.

Is the 5962-89687013A qualified for radiation-hardened applications?

The 5962-89687013A is not radiation-hardened (RH) but is radiation-tolerant per MIL-PRF-38535 Class B, including lot acceptance testing for total ionizing dose (TID) up to 100 krad(Si) and single-event latch-up (SEL) immunity per Method 1019. Full radiation-hardened variants require custom screening beyond standard Class B.
