Product details

Overview

5962-8775801RA from Texas Instruments is a military-grade octal bus transceiver with 3-state outputs, designed for bidirectional data bus isolation and level translation in harsh-environment systems. It operates from −55°C to 125°C, supports 2-V to 6-V V_CC, accepts input voltages up to 6 V, delivers max t_pd of 7 ns at 5 V, and features direction (DIR) and output-enable (OE) control logic for asynchronous two-way communication between A and B buses.

For engineers reviewing the 5962-8775801RA datasheet, 5962-8775801RA pinout, 5962-8775801RA application, or 5962-8775801RA equivalent, this device is selected for high-reliability aerospace, defense, and industrial control systems requiring MIL-PRF-38535 Class V compliance, wide-temperature operation, and robust bus isolation with controlled 3-state transitions.

Technical Context

The 5962-8775801RA implements dual 8-bit bidirectional data paths controlled by DIR and OE inputs: when OE is low, data flows noninverted from A to B or B to A depending on DIR state; when OE is high, both A and B ports enter high-impedance isolation. Its AC logic family ensures CMOS-compatible voltage thresholds and rail-to-rail input tolerance.

Designed per MIL-PRF-38535, the 5962-8775801RA undergoes full parametric testing across temperature, includes absolute maximum ratings up to 7 V supply and ±20 mA clamp current, and specifies guaranteed switching performance (t_PLH/t_PHL ≤ 7 ns at 5 V) and DC drive strength (±24 mA I_OL/I_OH) under military temperature extremes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2 V to 6 V - Enables interoperability across 3.3 V and 5 V logic domains without level shifters.
Operating Temperature	−55°C to 125°C - Qualified for extended-range military and aerospace platforms with no derating required.
Max Propagation Delay	7 ns at V_CC = 5 V - Supports high-speed bus handshaking in real-time avionics and radar subsystems.
Input Voltage Tolerance	Up to 6 V - Allows direct interface with legacy 5 V peripherals even when V_CC = 3.3 V.
Output Drive Strength	±24 mA at V_CC = 5 V - Sustains signal integrity driving 50 Ω transmission lines or multiple TTL loads.
3-State Leakage Current	±10 µA max at V_CC = 5.5 V - Ensures minimal bus contention during isolation in fault-tolerant architectures.
Package Type	CDIP (J) - Hermetically sealed ceramic dual in-line package for moisture resistance and thermal stability.

Pinout & Package

5962-8775801RA uses a 20-pin CDIP (J) package with 0.3-inch body width and through-hole mounting. The package meets MIL-STD-883 requirements for mechanical shock, vibration, and hermeticity.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	A1–A8 Inputs/Outputs	Port A bidirectional data lines - connected to local subsystem bus; direction determined by DIR.
11, 12, 13, 14, 15, 16, 17, 18	B1–B8 Inputs/Outputs	Port B bidirectional data lines - connected to remote or backplane bus; mirrors A port behavior.
9	DIR	Direction control input - low enables A→B transfer; high enables B→A transfer.
10	OE	Output-enable input - active-low; high forces all A/B pins into high-impedance state for bus isolation.
20	V_CC	Positive supply - must be decoupled locally; powers internal logic and output drivers.
19	GND	Ground reference - common return for all signals and power; requires low-inductance connection.

Key Features

Feature	Design Value
Fully tested per MIL-PRF-38535 Class V	100% parametric screening across −55°C to 125°C ensures reliability in mission-critical flight control systems.
Wide V_CC and input voltage range	2 V–6 V operation and 6 V input tolerance eliminate external level translators in mixed-voltage backplanes.
Controlled 3-state enable/disable timing	t_PZH/t_PZL ≤ 9 ns at 5 V prevents bus contention during hot-swap or mode transitions.
High noise immunity	V_IL = 1.65 V / V_IH = 3.85 V at V_CC = 5.5 V provides >1.3 V noise margin against EMI in avionics bays.
Hermetic CDIP packaging	Ceramic DIP (J) construction resists humidity, thermal cycling, and outgassing in vacuum or sealed enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54AC245FK	LCCC (FK) package instead of CDIP (J); identical electrical specs and MIL-PRF-38535 Class V qualification.	Better thermal performance (θ_JA ≈ 55°C/W vs. 70°C/W) and lower mass suitable for vibration-sensitive payloads.	Select SNJ54AC245FK when board space is constrained and surface-mount assembly is preferred over through-hole.
5962-8775801SA	CFP (W) package with same pinout and temperature range; slightly higher thermal resistance (θ_JA ≈ 75°C/W) but superior hermeticity for ultra-high-reliability vacuum environments.	Preferred for space applications requiring zero moisture permeability and long-term storage stability.	Choose 5962-8775801SA when CFP's enhanced hermetic seal and radiation hardness margin outweigh minor thermal trade-offs.

Compared with 5962-8775801RA, SNJ54AC245FK offers improved thermal management in compact layouts, while 5962-8775801SA provides superior hermetic protection for deep-space missions-both retain identical logic functionality, timing, and MIL-PRF-38535 compliance but differ in mechanical integration and environmental survivability.

FAQ

What is the qualified temperature range for the 5962-8775801RA?

The 5962-8775801RA is fully qualified for operation from −55°C to 125°C per MIL-PRF-38535 requirements. All electrical parameters-including propagation delay, drive strength, and leakage-are guaranteed across this full range without derating. This makes the 5962-8775801RA suitable for deployment in jet engine compartments, satellite payload bays, and desert-deployed tactical radios where ambient extremes are routine.

Does the 5962-8775801RA support mixed-voltage interfacing?

Yes, the 5962-8775801RA supports mixed-voltage interfacing: its V_CC operates from 2 V to 6 V, and its inputs tolerate voltages up to 6 V regardless of V_CC. For example, with V_CC = 3.3 V, the 5962-8775801RA can safely accept 5 V logic signals from legacy peripherals-eliminating external level shifters in hybrid 3.3 V/5 V avionics backplanes.

How is bus isolation ensured during power-up or power-down of the 5962-8775801RA?

Bus isolation during power sequencing is ensured by tying OE to V_CC through a pullup resistor. The 5962-8775801RA's internal design holds OE high during undervoltage conditions, forcing all A and B pins into high-impedance state until V_CC stabilizes. This prevents back-driving or contention on shared buses-a critical requirement in fault-tolerant flight control architectures.

What packaging and sealing standards apply to the 5962-8775801RA?

The 5962-8775801RA uses a hermetically sealed ceramic dual in-line package (CDIP, J) compliant with MIL-STD-883 methods 1014 and 1015 for leak testing. Its glass-to-metal seals and ceramic body provide zero moisture ingress, making it suitable for long-duration storage and operation in humid or pressurized aircraft bays without conformal coating.

Is the 5962-8775801RA pin-compatible with commercial SN74AC245 variants?

No-the 5962-8775801RA shares identical pinout and logic function with SN74AC245 but is not pin-compatible with commercial SOIC or TSSOP variants due to its 20-pin CDIP (J) footprint. However, it is mechanically and electrically compatible with other MIL-qualified versions like SNJ54AC245J and SNJ54AC245FK, enabling drop-in replacement within military-grade designs using through-hole or LCCC layouts.
