description
The TLV2354 consists of four independent, low-power comparators specifically designed for single power-supply applications and operateS with power-supply rails as low as 2 V. When powered from a 3-V supply, the typical supply current is only 240 µA.

The TLV2354 is designed using the Texas Instruments LinCMOSTM technology and, therefore, features an extremely high input impedance (typically greater than 1012 ), 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 TLV2354I is fully characterized for operation from 40°C to 85°C. The TLV2354M is fully characterized for operation from 55°C to 125°C. The TLV2354 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.

The D package is available taped and reeled. Add the suffix R to the device type (e.g., TLV2352IDR). The PW packages are only available left-ended taped and reeled (e.g., TLV2354IPW).
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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to network ground. 2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. 3. Short circuits from outputs to VDD can cause excessive heating and eventual device destruction.
