TLV2354M数据手册TI中文资料规格书

描述 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 uA. 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.
