Product details
Overview
5962-8765902CA from Texas Instruments is a military-grade quad comparator in a 14-pin ceramic DIP package, featuring LinCMOS™ technology, 200 µW typical supply power at 5 V, 2.5 µs typical propagation delay with 5-mV overdrive, and operation across −55°C to 125°C. It serves as a low-power, high-precision voltage threshold detector in radiation-tolerant avionics monitoring circuits.
For engineers reviewing the 5962-8765902CA datasheet, 5962-8765902CA pinout, 5962-8765902CA application, or 5962-8765902CA equivalent, key selection criteria include its open-drain MOS output stage, 5 mV max input offset voltage over temperature, single-supply operation from 4 V to 16 V, and compatibility with wired-OR logic and pull-up resistor interfacing in harsh-environment analog signal conditioning.
Technical Context
The 5962-8765902CA implements four independent differential comparators using Texas Instruments' LinCMOS™ process, delivering CMOS-level power efficiency (1/20th of LM139/LM339) without sacrificing speed. Its architecture features high input impedance (10¹² Ω typ), stable input offset voltage drift (0.23 µV/month), and on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
It operates exclusively with open-drain outputs requiring external pull-up resistors, enabling direct interface to TTL, CMOS, or mixed-voltage logic families and supporting wired-AND functionality. Input common-mode range extends to VDD−1.5 V across the full −55°C to 125°C military temperature range, ensuring reliable operation under rail-to-rail input stress conditions.

FAQ
What is the maximum allowable input voltage beyond the supply rails for 5962-8765902CA?
The absolute maximum ratings specify a differential input voltage of ±18 V and an input voltage range of −0.3 V to VDD. Inputs may exceed the supply rails only if current is limited to <5 mA to avoid forward-biasing ESD diodes. For reliable operation, inputs must stay within the common-mode range (0 V to VDD−1.5 V) to prevent output phase reversal. The 5962-8765902CA datasheet explicitly defines these limits in Section "Absolute Maximum Ratings".
Does 5962-8765902CA support rail-to-rail input operation?
No, the 5962-8765902CA does not support true rail-to-rail input operation. Its common-mode input voltage range is specified as 0 V to VDD−1.5 V across −55°C to 125°C. At 5 V supply, this means inputs must remain between 0 V and 3.5 V for guaranteed correct operation. Exceeding VDD−1.5 V risks output malfunction. This limitation is documented in the "Recommended Operating Conditions" table for the 5962-8765902CA.
Can 5962-8765902CA drive a 10 kΩ pull-up resistor to 12 V while maintaining logic levels?
Yes, the 5962-8765902CA's open-drain output can sink ≥20 mA per channel, allowing it to drive a 10 kΩ pull-up to 12 V with a worst-case VOL of 800 mV at 125°C and IOL = 6 mA. With 12 V pull-up, the output low voltage remains ≤0.8 V, ensuring clean TTL/CMOS-compatible logic low. This behavior is verified in the "Electrical Characteristics" table for the 5962-8765902CA under VDD = 5 V test conditions.
Is 5962-8765902CA qualified for space applications?
The 5962-8765902CA is MIL-PRF-38535 Class K qualified and screened to SMD 5962-87659, meeting requirements for high-reliability terrestrial military systems. While it has been used in some space-qualified assemblies, it is not officially QML-V or ESCC qualified for radiation-tolerant spaceflight. For spacecraft applications, users must perform additional lot-specific radiation testing. This distinction is clarified in TI's "Package Option Addendum" for the 5962-8765902CA.
What is the recommended decoupling capacitor for 5962-8765902CA?
Texas Instruments specifies a 0.1 µF ceramic capacitor placed as close as possible to the VDD and GND pins of the 5962-8765902CA to suppress high-frequency noise and stabilize supply voltage during fast output transitions. This value is cited in the "Application Information" section of the 5962-8765902CA datasheet and is mandatory for achieving specified propagation delay and noise immunity performance.
