Typical Application (continued)
9.2.2 Detailed Design Procedure
The H port signal from the master can go to 1 of the 4 slave ports depending on the select inputs S0 and S1.
The V_BIAS and V_REF can be determined from the Recommended Operating Conditions.
1. Recommended Input Conditions
– For specified high and low levels for all the input control pins, see V_IH and V_IL in the Recommended
Operating Conditions.
– Inputs are not overvoltage tolerant and should be below the valid V_DD.
2. Recommend Input/Output Conditions
– The absolute maximum continuous on state switch current for any I/O should not exceed ±100 mA
– The I/O voltage range should not be above V_DD and below ground.

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the
Recommended Operating Conditions.
Each V_CC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single
supply, TI recommends a 0.1-μF capacitor. If there are multiple V_CC pins, TI recommends a 0.01-μF or 0.022-μF
capacitor for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies
of noise. A 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed
as close to the power pin as possible for best results.
