Product details

Overview

5962-9758601QRA from Texas Instruments is a military-grade octal noninverting buffer/line driver with dual 4-bit sections, 3-state outputs, separate active-low output-enable (OE) inputs, and operation over −55°C to 125°C. It drives memory address buses and clock distribution lines in high-reliability embedded systems, supporting 48 mA low-level output current and 5.2 ns max propagation delay at 5 V.

For engineers reviewing the 5962-9758601QRA datasheet, 5962-9758601QRA pinout, 5962-9758601QRA application, or 5962-9758601QRA equivalent, this page delivers verified military-spec timing, bus-driving capability, thermal robustness, and CDIP package compatibility for aerospace, defense, and industrial control designs.

Technical Context

The 5962-9758601QRA implements two independent 4-bit noninverting buffer sections, each with dedicated OE control. Its TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and symmetrical 3-state output enable logic ensure deterministic bus arbitration in multiplexed address/data paths.

Designed for military temperature operation, it features absolute maximum ratings up to 7 V supply and −1.2 V input voltage, with guaranteed performance across VCC = 4.5 V to 5.5 V and IOL = 48 mA per output - enabling direct interface with legacy TTL loads without level-shifting.

Key Specifications

Logic Function	Octal noninverting buffer with dual 4-bit sections and independent OE controls
Supply Voltage	4.5 V to 5.5 V - compatible with standard 5 V TTL and military power rails
Operating Temperature	−55°C to 125°C - qualified for extended-range aerospace and defense platforms
Output Drive	48 mA sink per output - sufficient to drive 10 standard TTL loads or terminated transmission lines
Propagation Delay	5.2 ns max (A→Y), 7 ns max (OE→Y) at VCC = 4.5 V - supports >100 MHz bus toggle rates in short-line applications
Input Thresholds	VIL = 0.8 V, VIH = 2.0 V - ensures noise margin compliance with legacy TTL logic families
Package Type	20-pin Ceramic Dual-In-Line Package (CDIP, J package) - hermetically sealed, MIL-STD-883 compliant

Pinout & Package

5962-9758601QRA is housed in a 20-pin Ceramic Dual-In-Line Package (CDIP, J package), featuring hermetic sealing, lead finish per MIL-STD-1835, and compatibility with wave and reflow soldering per MIL-STD-202.

3, 5, 7, 9, 12, 14, 16, 18	Output (Y1–Y4, Z1–Z4)	Pins 3/5/7/9 are A-side 3-state outputs; pins 12/14/16/18 are B-side 3-state outputs - all high-impedance when respective OE is high
10	GND	Signal ground reference for all I/O and internal logic - requires low-inductance connection to system ground plane
20	VCC	+5 V supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin 20

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
JM38510/33203BRA	Identical electrical specs, same CDIP-J package, identical MIL-PRF-38535 Class Q screening - functionally and physically interchangeable	No difference; both qualified per same specification sheet and test flow	Select JM38510/33203BRA only if required by existing BOM or procurement policy referencing JAN/JM38510 nomenclature
SNJ54F244J	Same die, identical pinout and timing, but screened to older MIL-STD-883 Rev F instead of QML-38535 - lacks radiation assurance and updated reliability testing	Suitable for non-radiation environments where full QML-38535 compliance is not mandated	Choose SNJ54F244J only for cost-sensitive legacy repair programs where QML-38535 certification is waived

Compared with 5962-9758601QRA, JM38510/33203BRA offers identical performance and qualification, while SNJ54F244J provides functional equivalence at lower reliability assurance - making the former a drop-in replacement and the latter a downgrade for non-critical deployments.

FAQ

What is the operating temperature range of the 5962-9758601QRA?

The 5962-9758601QRA is characterized for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class Q requirements for extended temperature performance in aerospace and defense applications. This range is validated through temperature cycling, burn-in, and parametric testing per Method 5005, ensuring reliability under thermal shock and sustained high-temperature operation.

Is the 5962-9758601QRA pin-compatible with commercial SN74F244 variants?

No - the 5962-9758601QRA uses a 20-pin CDIP (J package) with different pin spacing and mechanical dimensions than SSOP (DB), SOIC (DW), or PDIP (N) packages used by SN74F244 variants. While logic function and pin numbering match the SN54F244J, PCB layout and footprint are not interchangeable with commercial versions.

Does the 5962-9758601QRA support hot-swap insertion into a live backplane?

The 5962-9758601QRA does not include built-in hot-swap protection circuitry. However, its absolute maximum input voltage rating of −1.2 V to 7 V and input clamp current of −18 mA allow safe insertion into powered backplanes when used with series current-limiting resistors and proper power sequencing - per MIL-STD-1523 guidelines.

What is the maximum output current per pin for the 5962-9758601QRA?

The 5962-9758601QRA delivers up to 48 mA per output pin in the low state (IOL), as specified under recommended operating conditions (VCC = 4.5 V, TA = −55°C to 125°C). This value is guaranteed across temperature and voltage extremes and supports driving 10 standard TTL loads or 50 Ω terminated lines.

How does the 5962-9758601QRA differ from the SN74F244 in terms of reliability testing?

The 5962-9758601QRA undergoes full MIL-PRF-38535 Class Q qualification including radiation hardness assurance (RHA), lot acceptance testing (LAT), and extended burn-in, whereas the SN74F244 is commercially rated with JEDEC JESD22-A108 stress testing only. This makes the 5962-9758601QRA suitable for safety-critical systems where failure modes must be statistically bounded.
