Product details

What this comparator brings to the board

The STMicroelectronics TS393CDT is a dual general-purpose comparator in an 8-SOIC package. It runs on a single supply from 2.7 V to 16 V, or split supplies from ±1.35 V to ±8 V, which covers most common logic and analog rails without an extra regulator. The open-drain output lets you pull up to any voltage within the supply range, making it handy for level-shifting or wired-OR connections. Input bias current maxes out at 1 pA at 5 V, so it won't load down high-impedance sources like pH probes or photodiode amplifiers. Quiescent current is held to 25 µA max, which keeps the power budget tight for battery-powered or low-standby designs.

Temperature grade and where it fits

Rated for 0°C to 70°C, this is a commercial-temperature part. It belongs in office equipment, consumer electronics, indoor instrumentation, and similar controlled environments. Not the choice for an engine bay, a rooftop telecom enclosure, or a freezer — for those, look at the industrial-grade variant in the same family.

Lifecycle and sourcing note

The TS393CDT is listed as Active and ROHS3 compliant. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time.

Frequently asked questions

Is TS393CDT compatible with LM393?

Yes, the TS393CDT is pin-compatible with the industry-standard LM393. Both are dual comparators in the same 8-SOIC footprint with open-drain outputs. The key difference is the TS393CDT's CMOS inputs — it has 1 pA max input bias current versus the LM393's bipolar inputs that draw around 25 nA. That matters when your source impedance is high. Supply range and output drive are similar, so it's a drop-in swap for most designs.

Does TS393CDT have open-drain output?

Yes, the output type is CMOS and open-drain. You need a pull-up resistor to the logic supply rail.

What package is TS393CDT?

It comes in an 8-SOIC package (0.154", 3.90 mm width), surface-mount. Also available in Tape & Reel or Cut Tape.

What is the difference between TS393CDT and TS393IDT?

The TS393IDT is the industrial-temperature version, rated -40°C to 125°C, while the TS393CDT is commercial-grade at 0°C to 70°C. Electrical specs are otherwise identical. Pick the IDT variant if your board sees outdoor or under-hood temperatures.
