When powered from a 3-V supply, the typical supply current is only 120 µA. The TLV2352 is designed using the Texas Instruments LinCMOS™ 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 circ...
