9 Power Supply Recommendations

These devices operate from an input voltage supply range between 1.7 V and 5.5 V.

10 Layout

10.1 Layout Guidelines

A power supply bypass capacitor of 100 nF is recommended when supply output impedance is high, supply

traces are long, or when excessive noise is expected on the supply lines. Bypass capacitors are also

recommended when the comparator output drives a long trace or is required to drive a capacitive load. Due to

the fast rising and falling edge rates and high-output sink and source capability of the TLV40x1 output stage,

higher than normal quiescent current can be drawn from the power supply when the output transitions. Under this

circumstance, the system would benefit from a bypass capacitor across the supply pins.
