The STMicroelectronics TS864IDT is a general-purpose quad comparator with four independent push-pull comparators. The 2µs propagation delay keeps up with moderate-speed control loops; the 16µA quiescent current per package (max) lets it sit in always-on monitoring circuits without draining the rail.
Push-pull output saves a resistor per channel
Each comparator drives a push-pull output stage—it sources and sinks current directly. The output swings rail-to-rail, so it interfaces cleanly with logic inputs on an MCU or FPGA without level translation at the same supply voltage. Input bias current is 300pA max at 5V, and input offset voltage is 15mV max at 5V—adequate for threshold detection and general-purpose comparison where precision below a few millivolts isn't required.
