VS is defined as VCC – VEE. Therefore, the supply voltages used to create VS can be single-ended or bipolar. For example, single-ended supply voltages of 5 V and 0 V and bipolar supply voltages of +2.5 V and –2.5 V create comparable operating voltages for VS. However, when bipolar supply voltages are used, it is important to realize that the logic low level of the comparator output is referenced to VEE. Output capacitive loading and output toggle rate will cause the average supply current to rise over the quiescent current. 10 Layout 10.1 Layout Guidelines To reduce PCB fabrication cost and improve reliability, TI recommends using a 4-mil via at the center pad connected to the ground trace or plane on the bottom layer. TI recommends a power-supply bypass capacitor of 100 nF 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 TLV703x and TLV704x output stages, higher than normal quiescent current can be drawn from the power supply. Under this circumstance, the system would benefit from a bypass capacitor across the supply pins. 10.2 Layout Example Figure 46.
