Product details

Overview

5962-9685801QRA from Texas Instruments is a military-grade octal buffer/driver with 3-state outputs, designed for bus driving and memory address register buffering in high-reliability systems. It operates from 4.5 V to 5.5 V, supports –55°C to +125°C temperature range, features TTL-compatible inputs, and uses dual active-low output-enable (OE1/OE2) control for channel grouping.

For engineers reviewing the 5962-9685801QRA datasheet, 5962-9685801QRA pinout, 5962-9685801QRA application, or 5962-9685801QRA equivalent, key selection criteria include its CDIP-20 package, MIL-PRF-38535 qualification, guaranteed 3-state propagation delay (tPZH/tPLZ ≤ 8.0 ns at CL = 15 pF), and latch-up immunity exceeding 250 mA per JESD 17.

Technical Context

The 5962-9685801QRA implements non-inverting 3-state buffering with dual independent enable logic: each OE input controls eight corresponding outputs via a 2-input AND gate with active-low polarity. A high on either OE1 or OE2 forces all associated outputs into high-impedance state, enabling flexible bus arbitration across two groups of four channels.

It adheres to MIL-PRF-38535 Class V requirements, includes ESD protection exceeding 2000-V HBM, 200-V MM, and 1000-V CDM, and maintains rail-to-rail output swing (VOH ≥ 3.8 V, VOL ≤ 0.44 V at IOL = 8 mA) under full military temperature and supply conditions.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9685801Q2A	LCCC-20 package (hermetic ceramic leadless chip carrier); higher thermal conductivity but requires solder reflow and X-ray inspection.	Better suited for high-vibration platforms (e.g., missile fins) where leaded packages risk mechanical fatigue.	Select 5962-9685801Q2A when board-level shock/vibe exceeds 20 g RMS and thermal cycling dominates reliability concerns.
5962-9685801QSA	CFP-20 package (ceramic flatpack); lower profile than CDIP, improved high-frequency signal integrity due to shorter leads.	Preferred for RF-dense assemblies (e.g., EW systems) where parasitic inductance must be minimized below 500 MHz.	Choose 5962-9685801QSA when layout constraints demand sub-3 mm height or when operating above 100 MHz clock harmonics.

Compared with 5962-9685801QRA, the Q2A offers superior thermal dissipation in conduction-cooled modules, while the QSA delivers tighter signal integrity for RF-adjacent digital routing-neither is pin-compatible, requiring PCB redesign, but all three share identical logic function, timing specs, and MIL-PRF-38535 Class V qualification.

FAQ

What is the maximum allowable supply voltage for 5962-9685801QRA?

The absolute maximum supply voltage for 5962-9685801QRA is 7 V, but the recommended operating range is strictly 4.5 V to 5.5 V per MIL-PRF-38535 specifications. Operation outside this range voids qualification compliance and risks parametric shift or latch-up, especially at temperature extremes. The 5962-9685801QRA must be powered within 4.5–5.5 V to maintain guaranteed timing and drive strength.

Does 5962-9685801QRA support hot-swap or live-insertion?

No, 5962-9685801QRA does not support hot-swap operation. Its inputs lack power-on reset circuitry or input clamping optimized for live insertion, and the CDIP-20 package has no built-in current-limiting during pin engagement. Applying VCC before establishing GND or enabling OE during insertion can cause undefined states or excessive current flow. System-level hot-swap requires external sequencing and current limiting-not provided by the 5962-9685801QRA itself.

How should unused inputs be handled on 5962-9685801QRA?

All unused inputs on 5962-9685801QRA must be tied to either VCC or GND to prevent floating nodes that induce shoot-through current, increased ICC, or erratic output behavior. TI recommends connecting unused A inputs to GND and unused OE inputs to VCC via pull-up resistors (minimum value determined by driver sink capability). This practice ensures predictable 3-state control and meets MIL-PRF-38535 test requirements for the 5962-9685801QRA.

Is 5962-9685801QRA RoHS-compliant?

No, 5962-9685801QRA is not RoHS-compliant. As a military-spec CDIP device manufactured to MIL-PRF-38535 Class V, it uses leaded solder and finishes incompatible with EU RoHS Directive 2011/65/EU. Its lead content is exempt under Annex III of the directive for high-reliability applications. Customers requiring RoHS compliance should consider commercial equivalents like SN74AHCT541DBR-but those lack MIL qualification and extended temperature rating.

What is the meaning of "QRA" in the part number 5962-9685801QRA?

The suffix "QRA" in 5962-9685801QRA denotes the specific packaging and screening variant: "QR" indicates the CDIP-20 package (J-body outline), and "A" signifies full MIL-PRF-38535 Class V qualification including extended temperature testing (–55°C to +125°C), burn-in, and lot traceability. This distinguishes it from other variants like Q2A (LCCC) or QSA (CFP), all sharing the same core logic but differing in mechanical form and test scope.
