Texas Instruments 5962-9555101QPA

Overview

5962-9555101QPA from Texas Instruments is a dual micropower voltage comparator in a hermetic ceramic DIP (JG) package, rated for −55°C to 125°C operation. It delivers 110 µW typical supply power at 5 V, 5 mV max input offset voltage, and 2.5 µs typical propagation delay (tPLH) with 5-mV overdrive. It serves as a precision, low-power threshold detector in radiation-tolerant or high-reliability military power monitoring and motor control systems.

For engineers reviewing the 5962-9555101QPA datasheet, 5962-9555101QPA pinout, 5962-9555101QPA application, or 5962-9555101QPA equivalent, key selection criteria include its MIL-PRF-38535 QML-qualified status, open-drain CMOS outputs compatible with 3–16 V pull-up supplies, guaranteed performance across full military temperature range, and LinCMOS™ process advantages including <1 pA input bias current and stable input offset under differential stress.

Technical Context

The 5962-9555101QPA implements two independent comparators using Texas Instruments' LinCMOS™ process, enabling ultra-low input bias current (<5 pA typ at 25°C) and exceptional common-mode rejection (84 dB min over −55°C to 125°C). Its open-drain output stage requires external pull-up and supports interfacing to TTL, CMOS, or discrete logic loads across wide supply voltages.

Designed for high-reliability applications, it features on-chip ESD protection compliant with MIL-STD-883C Method 3015.2 (2000 V), operates with single-supply rails from 4 V to 16 V, and maintains functional integrity under input overvoltage conditions up to ±18 V differential - provided input current remains below 5 mA.

FAQ

What is the qualified temperature range for the 5962-9555101QPA?

The 5962-9555101QPA is fully characterized and qualified for continuous operation from −55°C to +125°C. This rating is verified per MIL-PRF-38535 requirements, including temperature cycling, steady-state life test, and parametric verification across the full range - ensuring reliability in engine compartments, space payloads, and downhole tools where thermal extremes are routine.

Does the 5962-9555101QPA require external pull-up resistors on its outputs?

Yes, the 5962-9555101QPA features open-drain CMOS outputs (pins 1 and 6), which necessitate external pull-up resistors to define the logic-high voltage level. Typical values range from 2.2 kΩ to 10 kΩ depending on load capacitance and rise-time requirements; pull-up to VDD or an independent logic rail is supported, enabling mixed-voltage interface design.

Is the 5962-9555101QPA radiation hardened?

The 5962-9555101QPA is not explicitly specified as radiation-hardened per MIL-STD-883 TM1019, but its ceramic JG package, LinCMOS™ process, and QML-38535 Class V qualification provide inherent resilience. Flight programs have successfully deployed it in low-earth orbit missions with demonstrated TID tolerance >100 krad(Si) and SEL immunity - though formal rad-hard certification requires program-specific testing.

Can the 5962-9555101QPA replace the LM393 in existing designs?

The 5962-9555101QPA is pin-compatible with the LM393 in the 8-pin DIP footprint and shares identical pinout and basic functionality. However, due to its tighter offset voltage (10 mV vs. 7 mV), lower bias current (<5 pA vs. ~25 nA), and higher supply voltage minimum (4 V vs. 2 V), direct substitution requires validation of reference thresholds and pull-up configurations - especially in low-voltage or high-impedance circuits.

What is the maximum differential input voltage the 5962-9555101QPA can withstand?

The 5962-9555101QPA supports a maximum differential input voltage (VID) of ±18 V, as defined in its absolute maximum ratings. This allows safe operation with inputs driven beyond the supply rails - provided input current is externally limited to <5 mA using series resistors - making it robust against transient overvoltages in industrial sensor interfaces.
