7 Detailed Description

7.1 Overview

The TLV3501 and TLV3502 devices both feature high-speed response and include 6 mV of internal hysteresis for improved noise immunity with an input common-mode range that extends 0.2 V beyond the power-supply rails.

7.3 Feature Description

7.3.1 Operating Voltage

The TLV350x 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. These devices continue to function below this range, but performance is not specified.

7.3.2 Input Overvoltage Protection

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 comparator, as shown in Figure 15.

7.4 Device Functional Modes

7.4.1 Shutdown

A shutdown pin allows the device to go into idle when it is not in use. When the shutdown pin is high, the device draws approximately 2 μA, and the output goes to high impedance. When the shutdown pin is low, the TLV3501 is active. When the TLV3501 shutdown feature is not used, connect the shutdown pin to the most negative supply, as shown in Figure 16. Exiting shutdown mode requires approximately 100 ns. The TLV3502 does not have the shutdown feature.
