description The TLV2352 consists of two independent, IN+ low-power comparators specifically designed for

single power-supply applications and operates IN– with power-supply rails as low as 2 V. When powered from a 3-V supply, the typical supply current is only 120 µA. The TLV2352 is designed using the Texas Instruments Lin CMOS technology and therefore features an extremely high input impedance (typically greater than 1012 Ω), which allows direct interfacing with high-impedance sources. The outputs are N-channel open-drain configurations that require an external pullup resistor to provide a positive output voltage swing, and they can be connected to achieve positive-logic wired-AND relationships. The TLV2352I is fully characterized at 3 V and 5 V for operation from – 40°C to 85°C. The TLV2352M is fully characterized at 3 V and 5 V for operation from – 55°C to 125°C. The TLV2352 has internal electrostatic-discharge (ESD)-protection circuits and has been classified with a 1000-V ESD rating using Human Body Model testing. However, care should be exercised in handling this device as exposure to ESD may result in degradation of the device parametric performance.

These devices have limited built-in protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
