Texas Instruments 5962-9688201Q2A

Overview

5962-9688201Q2A from Texas Instruments is a military-grade quadruple low-voltage differential comparator using LinCMOS™ technology, designed for single-supply operation from 2 V to 8 V. It delivers 240 µA typical supply current at 3 V, features 10¹² Ω typical input impedance, 5 mV max input offset voltage at 25°C, and open-drain N-channel outputs requiring external pull-up. It serves in precision threshold detection within radiation-tolerant avionics power sequencing and missile guidance sensor interfaces.

For engineers reviewing the 5962-9688201Q2A datasheet, 5962-9688201Q2A pinout, 5962-9688201Q2A application, or 5962-9688201Q2A equivalent, key selection criteria include its –55°C to 125°C operating range, MIL-PRF-38535 qualification, 1000-V HBM ESD rating, and compatibility with TTL/MOS/CMOS logic families via open-drain outputs.

Technical Context

The 5962-9688201Q2A implements four independent comparators on a single die using Texas Instruments' LinCMOS™ process, enabling ultra-high input impedance and femtoamp-level bias current. Its input common-mode range includes ground across full temperature, supporting direct sensing of near-ground reference signals.

Each comparator output is an N-channel open-drain structure, requiring external pull-up resistors to define high-state voltage and enabling wired-AND logic configurations. Internal ESD protection circuits meet 1000-V human body model requirements without compromising input stage integrity.

FAQ

What is the operating temperature range of the 5962-9688201Q2A?

The 5962-9688201Q2A is fully characterized from –55°C to 125°C and qualified per MIL-PRF-38535 for extended-temperature military and aerospace applications. This range is validated across all electrical parameters including input offset voltage, supply current, and response time, ensuring consistent performance in jet engine bays, missile canisters, and satellite payload compartments.

Does the 5962-9688201Q2A require external pull-up resistors on its outputs?

Yes, the 5962-9688201Q2A features N-channel open-drain outputs that require external pull-up resistors to establish a defined high-state voltage. The value depends on load capacitance and required rise time; typical designs use 4.7 kΩ to 10 kΩ pull-ups to 3.3 V or 5 V rails. Without pull-ups, outputs remain floating and cannot drive logic-high signals.

Is the 5962-9688201Q2A pin-compatible with commercial TLV2354 variants?

No, the 5962-9688201Q2A uses a 20-pin LCCC package, whereas commercial TLV2354 variants (e.g., TLV2354ID, TLV2354IN) use 14-pin SOIC, PDIP, or TSSOP packages. Pin count, layout, and terminal assignment differ fundamentally-direct PCB replacement is not possible without redesign.

What is the maximum input common-mode voltage for the 5962-9688201Q2A at 3 V supply?

At VDD = 3 V, the 5962-9688201Q2A supports a common-mode input voltage range of 0 V to 1.75 V. This ground-inclusive range allows direct interfacing with sensors and references referenced to system ground, eliminating the need for level-shifting circuitry in low-voltage monitoring applications.

How is ESD protection implemented in the 5962-9688201Q2A?

The 5962-9688201Q2A integrates on-die electrostatic discharge (ESD) protection circuits on all input and output pins, achieving a 1000-V rating per the human body model (HBM). These structures clamp transient voltages without damaging the LinCMOS™ input transistors, though proper handling-such as shorting leads during storage-remains essential to preserve long-term parametric stability.
