TLC372

The Texas Instruments TLC372 is a dual differential comparator fabricated using CMOS technology. It is designed for single or dual-supply operation, with a wide supply voltage range from 3V to 16V. Each device features two independent voltage comparators with extremely high input impedance, typically greater than 10^12 Ohm, allowing direct interfacing with high-impedance sources.

The TLC372 offers a very low supply current drain, typically 150 uA at 5V, and a fast response time of 200 ns for a TTL-level input step. It includes built-in ESD protection, rated at 2000V per HBM testing. The common-mode input voltage range includes ground, and the outputs are compatible with TTL, MOS, and CMOS logic levels. The outputs are n-channel open-drain configurations, enabling wired-AND relationships.

This comparator is characterized for operation across an extended temperature range of -55°C to 125°C. It is pin-compatible with the LM393. The device is available in various packages including SOIC (D), TSSOP (PW), SOP (PS), and PDIP (P).

Applications for the TLC372 include general-purpose voltage comparison, threshold detection, and signal conditioning in systems requiring high input impedance and low power consumption.
