Product Overview
The TLC393 is a Texas Instruments dual micropower voltage comparator in the Signal_Chain category. Its device description specifies 2 independent comparators, and the output structure is an open-drain CMOS output. The part is documented with 110 µW typical power dissipation at VDD=5 V and 2.5 µs typical tPLH response time at 5 mV overdrive.
Recommended operating conditions vary by grade: TLC393C and TLC393I support 3 to 16 V supply operation, while TLC393Q supports 4 to 16 V. Common-mode input range is -0.2 to VDD-1.5 V for C and I grades, and 0 to VDD-1.5 V for Q grade. Operating free-air temperature ranges are 0 to 70 °C, -40 to 85 °C, and -40 to 125 °C respectively.
Package options include D small-outline, FK chip-carrier, JG ceramic DIP, P plastic DIP, and PW TSSOP. The open-drain output and 20 mA maximum low-level output current support comparator output interfacing in threshold, monitoring, and logic-level signaling circuits.
