Product details

Overview

5962-9075001MRA from Texas Instruments is a military-grade 16-bit inverted bus transceiver in ceramic dual-in-line package (CDIP), operating from −55°C to 125°C, with BiCMOS design enabling low ICCZ (10 mA max), 48 mA B-port sink current, and 3.4 V VOH at −3 mA - used for bidirectional asynchronous data isolation in avionics backplanes and radar timing interfaces.

For engineers reviewing the 5962-9075001MRA datasheet, 5962-9075001MRA pinout, 5962-9075001MRA application, or 5962-9075001MRA equivalent, key selection criteria include its dual-output-enable architecture for bus state retention, P-N-P input structure reducing DC loading, ESD protection >2000 V per MIL-STD-883C Method 3015, and compatibility with 5-V TTL/CMOS logic families.

Technical Context

The 5962-9075001MRA implements a dual-directional, inverting transceiver function with independent OEAB (A→B enable) and OEBA (B→A enable) controls, allowing isolated bidirectional data flow or simultaneous bus latching when both enables are active. Its BiCMOS process delivers TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and rail-to-rail output swing under load.

Timing behavior is defined by propagation delays ranging from 0.1 ns (tPHL A→B) to 7.2 ns (tPZH OEBA→A), with output disable/enable times under 11.5 ns. The device supports hot-swap-capable operation via controlled ICCZ (4–10 mA) and robust off-state leakage (IIL = −0.6 mA, IIH = 20 µA).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with legacy 5-V military power rails and tolerance to transient droop.
Operating Temperature	−55°C to 125°C - qualified per MIL-PRF-38535 for deployment in airborne and spaceborne systems.
B-Port Sink Current	64 mA max - drives heavy capacitive loads (e.g., long backplane traces) without signal degradation.
A-Port Source Current	−3 mA - sufficient to interface with standard TTL inputs while maintaining VOH ≥2.4 V.
Propagation Delay	0.1–6.9 ns - enables sub-10 ns synchronous bus handshaking in real-time control subsystems.
ICCZ Quiescent Current	10 mA max - minimizes standby power in always-on mission-critical communication nodes.
ESD Protection	>2000 V HBM - meets MIL-STD-883C Method 3015 for handling in uncontrolled environments.

Pinout & Package

Ceramic Dual-In-Line Package (CDIP), 20-pin, hermetically sealed, lead finish per MIL-STD-1835 (Call TI), RoHS exempt, MSL N/A.

Pin/Terminal	Circuit Role	Design Meaning
1, 20	VCC / GND	Power and ground reference pins - require local 0.1 µF ceramic decoupling per MIL-HDBK-454A.
2–9	A1–A8	Input/output port A - bidirectional, inverted data path; high-impedance when OEAB and OEBA both high.
11–18	B1–B8	Input/output port B - inverted mirror of A port; driven only when corresponding OE is asserted low.
10	OEAB	A→B output enable - active-low control; when low, enables A-to-B data transfer; when high, isolates A bus.
19	OEBA	B→A output enable - active-low control; when low, enables B-to-A data transfer; when high, isolates B bus.

Key Features

Feature	Design Value
BiCMOS Process Technology	Reduces ICCZ by >50% vs. bipolar-only equivalents, lowering thermal load in sealed chassis.
P-N-P Input Structure	Minimizes DC input loading (<0.6 mA IIL), preserving signal integrity on shared bus stubs.
Dual-Enable Bus Latching	Simultaneous OEAB/OEBA assertion holds both A and B bus states - eliminates need for external latch ICs.
MIL-STD-883C Qualified	Includes screening per Method 3015 (ESD), 2001 (steady-state life test), and 5005 (thermal shock).
Inverted Data Path	Guarantees logic inversion across all 16 channels - simplifies negative-logic handshake protocol implementation.

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9075001M2A	LCCC (FK) package, 20-pin, same electrical specs and temp range; different mechanical footprint and solder joint reliability profile.	Suitable for surface-mount PCBs with strict vibration resistance requirements (e.g., missile guidance systems).	Select when board assembly uses reflow-compatible ceramic leadless carriers and requires lower parasitic inductance than CDIP.
SNJ54BCT620AJ	Identical CDIP-20 package and marking; identical parametric performance; differs only in traceability documentation and lot-level screening depth.	Approved for non-mission-critical subsystems where full QML Class V screening is not mandated.	Choose for cost-sensitive programs requiring MIL-PRF-38535 compliance but not full QML certification.

Compared with 5962-9075001MRA, the 5962-9075001M2A offers superior high-frequency signal integrity in SMT layouts, while SNJ54BCT620AJ provides identical functionality with streamlined qualification-enabling trade-offs between mechanical ruggedness, production scalability, and certification rigor.

FAQ

What is the operating temperature range specified for the 5962-9075001MRA?

The 5962-9075001MRA is characterized for operation from −55°C to 125°C per MIL-PRF-38535, making it suitable for deployment in jet engine bays, satellite payload compartments, and artillery fire-control systems where ambient extremes exceed commercial grade limits. This range is validated through thermal shock, steady-state life, and burn-in testing.

Does the 5962-9075001MRA support non-inverting data transfer?

No, the 5962-9075001MRA provides inverted data at its outputs exclusively - both A→B and B→A paths perform logical inversion. This is inherent to the BCT620A architecture and confirmed in the functional truth table and logic diagram of the SCBS001B datasheet. For non-inverting operation, TI's BCT621A or equivalent must be selected.

What package type does the 5962-9075001MRA use, and is it hermetically sealed?

The 5962-9075001MRA uses a ceramic dual-in-line package (CDIP, drawing J), which is hermetically sealed per MIL-STD-1835. Its construction provides moisture resistance, mechanical stability under shock/vibration, and long-term reliability in vacuum or high-humidity environments typical of space and naval platforms.

Can the 5962-9075001MRA be used with 3.3-V logic systems?

No - the 5962-9075001MRA is designed for 5-V operation only, with absolute maximum VCC of 7 V and recommended VCC range of 4.5 V to 5.5 V. Its input thresholds (VIH = 2 V, VIL = 0.8 V) and output drive strength assume 5-V rail conditions; interfacing with 3.3-V systems requires level-shifting circuitry or a compatible 3.3-V transceiver such as the SN74LVC624.

How does the dual-output-enable feature of the 5962-9075001MRA enable bus state retention?

When both OEAB and OEBA are held low, the 5962-9075001MRA actively drives both A and B buses. If all other drivers on those buses enter high-impedance states, each port reinforces its own value - effectively latching the last transferred data without external storage. This behavior is explicitly documented in the device description and function table of the SCBS001B datasheet.
