WRITING TO THE ADG2188
INPUT SHIFT REGISTER
The input shift register is 24 bits wide. A 3-byte write is necessary when writing to this register and is done under the control of the serial
clock input, SCL. The contents of the three bytes of the input shift register are shown in Figure 33 and described in Table 6.

Description
DB23 to DB17
1110xxx
The MSBs of the ADG2188 are set to 1110. The LSBs of the address byte are set by the
state of the three address pins, Pin A0, Pin A1, and Pin A2.
DB16
R/W
Controls whether the ADG2188 slave device is read from or written to.
If R/W = 1, the ADG2188 is being read from.
If R/W = 0, the ADG2188 is being written to.
DB15
Data
Controls whether the switch is to be open (off ) or closed (on).
If Data = 0, the switch is open/off.
If Data = 1, the switch is closed/on.
DB14 to DB11
AX3 to AX0
Controls I/Os X0 to X7. See Table 7 for the decode truth table.
DB10 to DB8
AY2 to AY0
Controls I/Os Y0 to Y7. See Table 7 for the decode truth table.
DB7 to DB1
X
Don’t care.
DB0
LDSW
This bit is useful when a number of switches need to be updated simultaneously.
If LDSW = 1, the switch position changes after the new word is read in.
If LDSW = 0, the input data is latched, but the switch position is not changed.
As shown in Table 6, Bit DB11 to Bit DB14 control the X input/output lines, while Bit DB8 to Bit DB10 control the Y input/output lines.
Table 7 shows the truth table for these bits. Note that the full coding sequence is written out for Channel Y0, and Channel Y1 to Channel Y7
follow a similar pattern. Note also that the RESET pin must be high when writing to the device.
