Smart 16-Channel Low-Side Switch

Control of the Device

Figure 19

OR Operation between IN and Serial Input

This OR operation enables the serial interface to switch the channel ON, even though the corresponding parallel

input might be in the off state.

SPI Priority for ON-State

Also parallel control of the outputs is possible without an SPI input.

The OR-function is the default Boolean operation if the device restarts after a Reset, or when the supply voltage

is switched on for the first time.

If the OR operation is programmed it is latched until it is overwritten by the AND operation.

Control Byte No. 5 and 10

With HHHH LLLL as the control word, each of the input signals IN1 to IN4 are ‘AND’ed with the corresponding SI

data bits.

With HHHH HHHH as the control word, each of the input signals IN9 to IN12 are ‘AND’ed with the corresponding

SI data bits.
