The SN3257-Q1 can be operated without any external components except for the supply decoupling capacitors. The SN3257-Q1 has internal weak pull-down resistors (6 MΩ) to GND so that it powers-on with the switches in a known state. All inputs signals passing through the switch must fall within the recommended operating conditions of the SN3257-Q1 including signal range and continuous current. This design example can support SPI signals that range from 0 V to 3.3 V when the device is powered. This example can also utilize the Powered-off Protection feature and the inputs can range from 0 V to 3.6 V when V_DD = 0 V. The maximum continuous current can be 25 mA. Due to the voltage range and high speed capability, the SN3257-Q1 example is suitable for use in SPI, JTAG, and I2S applications.
