www.ti.com
Power Up
In the Pin Mode, when the power is applied to the device power suppy pins, the DS10CP154A enters the Power
Up mode when the PWDN pin is set to logic H. When in the Power Down mode (PWDN pin is set to logic L), all
circuitry is shut down except the minimum required circuitry for the LOS and SMBus Slave operation.
Switch Configuration
In the Pin Mode, the DS10CP154A operates as a fully pin-configurable crosspoint switch. The following truth
tables illustrate how the swich can be configured with external pins.
