Texas Instruments TLC352 Dual, Low Voltage, LinCMOS(TM) Differential Comparator TLC352IPWG4

The TLC352 is a dual, low voltage LinCMOS differential comparator designed for single or dual supply operation, with a supply voltage range of 2.7V to 18V. It features a low supply current drain of 150¬µA typical at 5V, making it suitable for low-power applications. The device has a high input impedance of 10^{12}Oc and an extremely low input bias current of 5pA, allowing direct interfacing with high-impedance sources. The output configuration is n-channel open-drain, compatible with TTL, MOS, and CMOS logic levels, and can be used to create positive-logic wired-AND relationships. The TLC352 includes built-in electrostatic discharge (ESD) protection rated at 2000V, although careful handling is advised to prevent performance degradation. It is characterized for operation over a temperature range of 0¬8C to 70¬8C for the TLC352C variant and -40¬8C to 85¬8C for the TLC352I variant. This device is particularly well-suited for low-voltage battery applications due to its operational flexibility and low power consumption.
