Product details

Overview

5962-9322701QRA from Texas Instruments is a military-grade octal noninverting buffer/driver with 3-state outputs, designed for high-density bus interfacing in aerospace and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs (IOH/IOL), features EPIC-II^B BiCMOS architecture for low power dissipation, and supports TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) at 4.5–5.5 V supply.

For engineers reviewing the 5962-9322701QRA datasheet, 5962-9322701QRA pinout, 5962-9322701QRA application, or 5962-9322701QRA equivalent, key selection criteria include its CDIP-J package compatibility, guaranteed latch-up immunity (>500 mA per JESD-17), output ground bounce <1 V, and dual active-low OE control enabling independent 4-bit channel gating in memory address and clock distribution circuits.

Technical Context

The 5962-9322701QRA implements two independent 4-bit noninverting buffer sections (1A→1Y, 2A→2Y), each controlled by dedicated active-low output-enable inputs (1OE, 2OE). Its EPIC-II^B BiCMOS process enables symmetrical drive strength (–32 mA IOH, 64 mA IOL) while maintaining TTL-level input compatibility and fast propagation delays (tPLH/tPHL ≤ 4.4 ns at 5 V).

Input clamping (–18 mA IIK), output clamping (–50 mA IOK), and ESD protection (>2000 V per MIL-STD-883 Method 3015) ensure robust operation in harsh environments. The device requires external pullup/pulldown resistors on OE pins to guarantee high-impedance state during power sequencing - minimum resistor values are determined by driver current-sinking/sourcing capability.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures stable operation under regulated 5-V rail with ±10% tolerance in avionics power systems.
Operating Temperature	–55°C to 125°C - qualified for full military temperature range, suitable for engine bay, radar, and space-qualified electronics.
Output Drive	–32 mA IOH / 64 mA IOL - drives heavy capacitive loads (e.g., >50 pF buses) without signal degradation or timing skew.
Propagation Delay	tPLH/tPHL ≤ 4.4 ns (VCC = 5 V, CL = 50 pF) - supports >100 MHz bus toggle rates in synchronous memory interfaces.
Input Thresholds	VIH = 2 V, VIL = 0.8 V - fully compatible with standard TTL logic families, eliminating level-shifting requirements.
Ground Bounce	VOLP < 1 V at VCC = 5 V, TA = 25°C - minimizes noise coupling into shared ground planes in multi-channel digital systems.
ESD Protection	>2000 V per MIL-STD-883 Method 3015 - withstands handling and field electrostatic discharge in maintenance and deployment scenarios.

Pinout & Package

5962-9322701QRA uses a 20-pin Ceramic Dual-In-Line Package (CDIP-J), hermetically sealed for high-reliability military applications. Package dimensions conform to JEDEC MS-001, with 0.3-inch body width and 0.1-inch lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1, 19	1OE, 2OE	Active-low output-enable controls for Channel 1 and Channel 2 - must be pulled high via resistor to maintain high-Z state during power-up.
2–5, 11–14	1A1–1A4, 2A1–2A4	Noninverting input terminals - accept TTL/CMOS logic levels; unused inputs must be tied to VCC or GND.
18, 16, 14, 12, 9, 7, 5, 3	1Y1–1Y4, 2Y1–2Y4	3-state buffered outputs - present inverted logic only when corresponding OE is low; high-Z otherwise.
10	GND	Digital ground reference - requires low-inductance connection to system ground plane to suppress switching noise.
20	VCC	Positive supply terminal - bypassed with 0.1 µF ceramic capacitor near pin to stabilize transient current demands.

Key Features

Feature	Design Value
EPIC-II^B BiCMOS Process	Reduces static power consumption vs. bipolar-only designs while retaining high-speed edge rates and drive strength.
Dual Independent OE Control	Enables selective 4-bit channel isolation - critical for time-multiplexed address/data bus sharing in MIL-STD-1553 or ARINC-429 interface modules.
Latch-Up Immunity	Exceeds 500 mA per JESD-17 - prevents destructive parasitic SCR activation during voltage transients in rad-hard systems.
High-Drive Outputs	–32 mA IOH / 64 mA IOL - drives up to 10 standard TTL loads or long PCB traces without external buffers.
Output Ground Bounce Suppression	VOLP < 1 V - maintains signal integrity in multi-output switching events common in synchronous bus drivers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9322701Q2A	LCCC-FK package (20-pin ceramic leadless chip carrier); same electrical specs and temp range.	Suitable for surface-mount high-density assemblies where through-hole CDIP is mechanically incompatible.	Select when board space constraints or vibration resistance require hermetic SMT packaging over through-hole CDIP.
5962-9322701QSA	CFP-W package (20-pin ceramic flatpack); identical DC/AC performance and military qualification.	Preferred for hybrid microcircuit integration or applications requiring low-profile mounting (<3.3 mm height).	Choose for legacy hybrid assembly processes or when Z-height limitation excludes CDIP-J's 4.95-mm profile.

Compared with 5962-9322701QRA, the Q2A offers superior thermal dissipation in conduction-cooled modules due to FK package's lower θJA, while the QSA provides mechanical stability in shock-prone environments via CFP's rigid leadframe - all three share identical logic function, timing, and reliability screening per MIL-PRF-38535 Class V.

FAQ

What is the maximum output current rating for 5962-9322701QRA?

The 5962-9322701QRA supports –32 mA high-level output current (IOH) and 64 mA low-level output current (IOL) per pin under recommended operating conditions. These values are validated across the full –55°C to 125°C temperature range and ensure reliable driving of multiple TTL loads or moderate capacitive bus structures without derating.

Does 5962-9322701QRA require external pull-up resistors on its OE pins?

Yes - to guarantee high-impedance state during power-up or power-down, both 1OE and 2OE pins of the 5962-9322701QRA must be tied to VCC via pull-up resistors. The minimum resistor value depends on the current-sinking capability of the driving source; TI recommends verifying against the device's IIH specification (±1 µA max) to avoid excessive static current draw.

Is 5962-9322701QRA compliant with MIL-PRF-38535 Class V screening?

Yes - the 5962-9322701QRA is manufactured and tested to MIL-PRF-38535 Class V requirements, including extended temperature cycling, burn-in, and radiation hardness assurance protocols. This certification confirms its suitability for critical aerospace and defense applications where failure modes must be rigorously excluded.

What is the typical propagation delay for 5962-9322701QRA at 5 V supply?

At VCC = 5 V and TA = 25°C with CL = 50 pF, the 5962-9322701QRA exhibits typical propagation delays of 2.6 ns (tPLH) and 2.9 ns (tPHL) from input to output. These values are consistent across all eight channels and remain within 4.4 ns maximum across the full military temperature range.

Can 5962-9322701QRA be used interchangeably with commercial-grade SN74ABT241A devices?

No - while electrically similar, the 5962-9322701QRA is a military-specification part with enhanced screening, wider temperature range (–55°C to 125°C), and CDIP-J hermetic packaging, whereas SN74ABT241A is commercial-grade (–40°C to 85°C) in plastic packages. Substitution requires full requalification per DO-254 or MIL-HDBK-217F due to reliability and environmental differences.
