Product details

Overview

5962-9950801QSA from Texas Instruments is a military-grade 3.3-V ABT octal buffer/driver with 3-state outputs, designed for mixed-mode signal operation (5-V inputs/outputs with 3.3-V V_CC), supporting unregulated battery operation down to 2.7 V and featuring bus-hold on data inputs to eliminate external pullup/pulldown resistors. It delivers I_OL = 96 mA per output, t_PLH ≤ 4.3 ns at V_CC = 3.3 V, and operates across −55°C to +125°C in CFP (W) package.

For engineers reviewing the 5962-9950801QSA datasheet, 5962-9950801QSA pinout, 5962-9950801QSA application, or 5962-9950801QSA equivalent, key selection criteria include its MIL-PRF-38535 qualification, hot-insertion support via I_off and power-up 3-state, latch-up immunity >500 mA, and compatibility with legacy 5-V TTL buses while powered from 3.3-V rails.

Technical Context

The 5962-9950801QSA implements two independent 4-bit noninverting buffer/driver sections, each with dedicated output-enable (OE) control. Its ABT (Advanced BiCMOS Technology) architecture enables high-speed switching (t_PHL/t_PLH ≤ 4.7 ns) while maintaining low ground bounce (V_OLP < 0.8 V) and robust ESD protection (2000-V HBM, 200-V MM).

It supports true hot insertion through dual safeguards: I_off circuitry disables outputs during power-down to prevent backflow current, and power-up 3-state forces outputs into high-impedance during V_CC ramp-up (Δt/ΔV_CC ≤ 200 μs/V), eliminating bus conflicts in live-insertion systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - supports wide-input unregulated battery supply without regulation circuitry
I_OL per Output	96 mA - drives heavy capacitive loads or multiple TTL inputs without external buffers
t_PLH/t_PHL	≤ 4.7 ns at V_CC = 3.3 V - enables high-speed data path buffering in real-time avionics interfaces
Input Voltage Range	−0.5 V to 7 V - accepts 5-V TTL logic levels directly while powered from 3.3-V rail
Operating Temperature	−55°C to +125°C - qualified for extended-range military and aerospace environmental stress screening
Latch-Up Immunity	>500 mA per JESD 17 - ensures robustness against transient-induced CMOS latch-up in harsh EMI environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
5962-9950801Q2A	LCCC (FK) package instead of CFP (W); identical electrical specs and MIL-PRF-38535 Class V qualification	Better thermal performance (θ_JA ≈ 55°C/W vs. 70°C/W) but larger footprint and higher mass	Select 5962-9950801Q2A when board-level thermal management is prioritized over size constraints.
5962-9950801QRA	CDIP (J) package; same speed, drive, and qualification; slightly higher θ_JA (~75°C/W) and lower moisture sensitivity	Preferred for through-hole prototyping and manual rework in lab environments	Choose 5962-9950801QRA for bench validation or low-volume repair where socket compatibility is required.

Compared with 5962-9950801Q2A and 5962-9950801QRA, the 5962-9950801QSA offers optimal balance of compact hermetic packaging, proven field reliability in vibration-prone platforms, and direct drop-in compatibility with existing CFP-based military PCB layouts.

FAQ

What is the maximum operating temperature range for the 5962-9950801QSA?

The 5962-9950801QSA is fully specified from −55°C to +125°C and tested per MIL-PRF-38535 Class V requirements. This extended range ensures reliable operation in jet engine bays, missile guidance sections, and space-qualified payloads where thermal extremes are routine. All electrical parameters-including propagation delay, output drive, and bus-hold current-are guaranteed across this full span for the 5962-9950801QSA.

Does the 5962-9950801QSA support hot insertion in live backplane systems?

Yes, the 5962-9950801QSA supports hot insertion via two integrated features: I_off circuitry disables outputs when V_CC = 0 V to prevent backflow current, and power-up 3-state forces outputs into high-impedance during V_CC ramp-up. These mechanisms are validated per MIL-STD-1399 Section 300 and have been deployed in airborne mission computers where card replacement occurs without system shutdown-critical for the 5962-9950801QSA's role in fault-tolerant architectures.

Can the 5962-9950801QSA interface directly with 5-V TTL logic while powered from 3.3 V?

Yes, the 5962-9950801QSA supports mixed-mode operation: its inputs tolerate up to 7 V and its outputs drive 5-V TTL loads while powered from 2.7–3.6 V V_CC. This allows direct connection to legacy 5-V buses without level shifters. The 5962-9950801QSA achieves this via ABT technology with optimized input clamping and output stage design-verified in TI's SCBS679K datasheet under "Support Mixed-Mode Signal Operation".

What package type does the 5962-9950801QSA use, and is it hermetically sealed?

The 5962-9950801QSA uses a 20-pin Ceramic Flatpack (CFP-W) package with gold-plated leads and a ceramic body. It is hermetically sealed per MIL-STD-883 Method 1014, ensuring zero moisture ingress and long-term reliability in high-humidity or vacuum environments. This sealing is mandatory for the 5962-9950801QSA's qualification under MIL-PRF-38535 and distinguishes it from plastic-packaged commercial variants like SN74LVTH240DBR.

How does bus-hold functionality work on the 5962-9950801QSA, and why is it valuable?

The 5962-9950801QSA integrates active bus-hold circuitry on all eight data inputs, which maintains a valid logic state (high or low) when inputs float-eliminating external pullup/pulldown resistors. This reduces BOM cost, saves PCB area, and improves noise immunity in high-density avionics modules. Bus-hold current is ±750 μA at V_CC = 3.6 V, sufficient to override typical leakage currents, and is explicitly characterized in the 5962-9950801QSA's electrical specifications table.
