The device maintains response times comparable to the LM393 while dramatically reducing power consumption. The CMOS input stage provides ultra-low input bias current of 1 pA typical, making it suitable for high-impedance sensor interfaces. The input common-mode voltage range includes ground, enabling single-supply operation from 2.7V to 16V. The open-drain output is compatible with wired-OR configurations and can interface with logic levels above or below the supply voltage. The TS393 is pin-compatible with the LM393, enabling direct replacement in power-sensitive applications.","working_principle":"The TS393 operates through three key subsystems:\n\n1. Input Stage: A CMOS differential pair compares the two input voltages (IN+ and IN-). The high-impedance CMOS inputs draw only 1 pA of bias current, enabling connection to high-impedance signal sources without loading effects. The input common-mode range extends from ground to VCC-1.5V, allowing ground-referenced sensing.\n\n2. Comparison Logic: The differential amplifier stage amplifies the voltage difference between IN+ and IN-. When IN+ exceeds IN-, the comparator output transitions. The propagation delay is comparable to the LM393 despite the dramatically lower supply current, achieved through optimized CMOS design. Internal hysteresis can be added externally via positive feedback.\n\n3. Output Stage: An open-drain NMOS transistor provides the output. When the comparator detects IN+ < IN-, the output transistor turns on, pulling the output low. When IN+ > IN-, the output transistor turns off, and the output floats (requires an external pull-up resistor). This open-drain configuration supports wired-OR connections and level shifting to voltages different from the comparator supply.","pin_description":"
