8 Detailed Description

8.1 Overview

The TLV3201-Q1 and TLV3202-Q1 devices feature 40-ns response time and include 1.2 mV of internal hysteresis for improved noise immunity with an input common-mode range that extends 0.2 V beyond the power-supply rails.

8.3 Feature Description

8.3.1 Operating Voltage

The TLV3201-Q1 and TLV3202-Q1 comparators are specified for use on a single supply from 2.7 V to 5.5 V (or a dual supply from ±1.35 V to ±2.75 V) over a temperature range of −40°C to +125°C. The device continues to function below this range, but performance is not specified.

8.3.2 Input Overvoltage Protection

The device inputs are protected by electrostatic discharge (ESD) diodes that conduct if the input voltages exceed the power supplies by more than approximately 300 mV. Momentary voltages greater than 300 mV beyond the power supply can be tolerated if the input current is limited to 10 mA. This limiting is easily accomplished with a small input resistor in series with the input to the comparator.

8.4 Device Functional Modes

The device is fully functional when powered by rail-to-rail supply voltage greater than 2.7 V.
