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 mA.
The TLV2354 is designed using the Texas Instruments LinCMOSE technology and, therefore, features an
extremely high input impedance (typically greater than 1012 W), 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.
