TLV3501-Q1 SBOS533A – SEPTEMBER 2010 – REVISED SEPTEMBER 2010 www.ti.com APPLICATION INFORMATION The TLV3501-Q1 features high-speed response and includes 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. 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 about 2 mA and the output goes to high impedance.

TLV3501-Q1 www.ti.com SBOS533A – SEPTEMBER 2010 – REVISED SEPTEMBER 2010 Input Over-Voltage 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 17.

TLV3501-Q1 SBOS533A – SEPTEMBER 2010 – REVISED SEPTEMBER 2010 www.ti.com High-Speed Window Comparator A window comparator circuit is used to determine when a signal is between two voltages. The TLV3501-Q1 can readily be used to create a high-speed window comparator. VHI is the upper voltage threshold, and VLO is the lower voltage threshold. When VIN is between these two thresholds, the output in Figure 19 is high. Figure 20 shows a simple means of obtaining an active low output.

TLV3501-Q1 www.ti.com SBOS533A – SEPTEMBER 2010 – REVISED SEPTEMBER 2010 PCB Layout For any high-speed comparator or amplifier, proper design and printed circuit board (PCB) layout are necessary for optimal performance. Excess stray capacitance on the active input, or improper grounding, can limit the maximum performance of high-speed circuitry. Minimizing resistance from the signal source to the comparator input is necessary in order to minimize the propagation delay of the complete circuit.
