Serial Timing Diagram
SLATCH
Programming Model
The ISL59534 is configured by a series of 16-bit serial control words. The three MSBs (B15-13) of each serial word determine the
basic command:
Mapping Inputs to Outputs
Inputs are mapped to their desired outputs using the input/output control word. Its format is:
I
4
:I
0
form the 5-bit word indicating the input channel (0 to 31), and O
3
:O
0
determine the output channel which that input channel
will map to. One input can be mapped to one or multiple outputs. To fully program the ISL59534, 32 INPUT/OUTPUT words must
be transmitted - one for each input channel.

SLATCH falling edge timing/placement is a “don’t care.”
Serial data is latched only on rising edge of SLATCH.

SDO = SDI delayed by 15.5 SCLKs to allow daisy-chaining of multiple ISL59534s. SDO changes on the falling edge of SCLK.
