TLC374CDR

The TLC374CDR from Texas Instruments is a quadruple differential comparator fabricated using LinCMOS technology. It is designed to operate from a single power supply or dual supplies with a voltage difference of 2 V to 18 V. This comparator offers a fast response time of 200 ns and features extremely high input impedance, typically greater than 10^12, allowing direct interfacing with high-impedance sources. The device has a very low supply current drain of 0.3 mA typical at 5 V. The operating temperature range is from -55°C to 125°C. The outputs are n-channel open-drain configurations and are compatible with TTL, MOS, and CMOS logic levels. The TLC374CDR is supplied in a 14-SOIC package and is pin-compatible with the LM339.

Key electrical characteristics include an offset voltage of 5 mV maximum at 25°C, an input bias current of 5 pA typical, and a supply current of 0.3 mA typical at 5V. The propagation delay is 200 ns typical for a TTL-level input step. The common-mode input voltage range includes ground. The device is suitable for various applications requiring precise voltage comparison.

Mounting is via surface mount technology. The 14-SOIC package has a width of 3.90 mm. The device is RoHS3 compliant and has an MSL rating of 1.
