TLC352ID

The Texas Instruments TLC352ID is a dual-supply comparator fabricated using LinCMOS technology. It consists of two independent voltage comparators, each capable of operating from a single power supply or dual supplies with a voltage difference between 1.4V and 18V. This device is suitable for low-voltage battery applications due to its ability to operate from a 1.4V supply.

Key electrical characteristics include a wide supply voltage range of 1.5V to 18V, very low supply current drain (150 µA typical at 5V, 65 µA typical at 1.4V), and extremely high input impedance (typically greater than 10^12 Ω). It also features an ultralow input bias current of 5 pA typical and an input offset voltage change of typically 0.23 µV/Month under worst-case conditions.

The TLC352ID has internal electrostatic discharge (ESD) protection circuits and is pin-compatible with the LM393. The outputs are n-channel open-drain configurations, allowing for wired-AND logic connections. This comparator is characterized for operation over the industrial temperature range of -40°C to 85°C.

Packaged in an 8-SOIC surface mount package, the TLC352ID is designed for applications requiring precise voltage comparison with minimal power consumption and high input impedance.
