Texas Instruments 5962-87659022A

Overview

5962-87659022A from Texas Instruments is a quad differential voltage comparator with LinCMOS™ process technology, designed for military-grade single-supply operation from −55°C to 125°C. It delivers 200 µW typical supply power at 5 V, 2.5 µs typical propagation delay with 5-mV overdrive, and 10¹² Ω typical input impedance - enabling precision threshold detection in radiation-tolerant avionics power supervisors and missile guidance analog front-ends.

For engineers reviewing the 5962-87659022A datasheet, 5962-87659022A pinout, 5962-87659022A application, or 5962-87659022A equivalent, key selection criteria include its open-drain CMOS output stage, ±18 V differential input rating, 5 mV max input offset voltage over temperature, and compatibility with wired-OR logic and pull-up resistor interfacing in high-reliability analog signal conditioning circuits.

Technical Context

The 5962-87659022A implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering stable input offset voltage (≤5 mV over −55°C to 125°C) and ultra-low bias current (≤30 nA at 125°C). Its open-drain output architecture requires external pull-up and supports mixed-voltage logic interfacing.

It operates across a 4 V to 16 V supply range with common-mode input voltage spanning 0 V to (VDD − 1.5 V), and features on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2 - critical for deployment in unregulated power rail monitoring and fault-detection systems where input transients are common.

FAQ

What is the maximum allowable differential input voltage for the 5962-87659022A?

The 5962-87659022A supports a maximum differential input voltage of ±18 V, defined as the voltage at IN+ with respect to IN−. This rating applies across the full operating temperature range of −55°C to 125°C and enables direct interfacing with unconditioned sensor outputs or high-swing industrial signals without external attenuation. Exceeding ±18 V may cause irreversible damage to the input ESD protection structure.

Does the 5962-87659022A require external pull-up resistors on its outputs?

Yes, the 5962-87659022A features open-drain CMOS outputs and requires external pull-up resistors to establish valid logic-high states. Typical values range from 2.2 kΩ to 10 kΩ depending on rise-time requirements and supply voltage. The device itself does not provide internal pull-ups, and omission of external resistors results in undefined output states during high-level transitions.

Can the 5962-87659022A operate from a 3-V supply?

No, the 5962-87659022A has a minimum recommended supply voltage of 4 V per its absolute maximum ratings and electrical specifications. While some variants like TLC339C support 3 V operation, the 5962-87659022A (TLC139MFK) is characterized only from 4 V to 16 V. Operating below 4 V risks unreliable output switching, increased propagation delay, and potential functional failure.

Is the 5962-87659022A pin-compatible with standard LM339 devices?

No, the 5962-87659022A is not pin-compatible with the LM339 due to its 20-pin LCCC (FK) package versus the LM339's 14-pin DIP or SOIC footprint. Although functionally similar as a quad comparator, the 5962-87659022A uses a different pinout, including dedicated NC pins and distinct power/ground distribution - requiring custom PCB layout and cannot serve as a drop-in replacement.

What is the input common-mode voltage range for the 5962-87659022A at 125°C?

At 125°C, the input common-mode voltage range for the 5962-87659022A is 0 V to (VDD − 1.5 V), as specified in the recommended operating conditions. For example, with VDD = 12 V, the valid input range is 0 V to 10.5 V. This specification ensures proper comparator operation even under worst-case thermal stress, unlike commercial-grade variants that narrow this range at temperature extremes.
