description

The TLV2352 consists of two 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 120 mA.

The TLV2352 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 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.
