Applications Information
Logic Levels
The devices’ digital interface inputs CLK, DIN, LE, and
CLR are tolerant of up to +6V, independent of the VDD
supply voltage, allowing compatibility with higher voltage
controllers.
Daisy Chaining Multiple Devices
Digital output DOUT is provided to allow the connec-
tion of multiple devices by daisy-chaining (Figure 3).
Connect each DOUT to the DIN of the subsequent device
in the chain. Connect CLK, LE, and CLR inputs of all
devices, and drive LE logic-low to update all devices
simultaneously. Drive CLR high to open all the switches
simultaneously. Additional shift registers may be included
anywhere in series with the MAX4800A/MAX4802A data
chain.
Supply Sequencing and Bypassing
The devices do not require special sequencing of the
VDD, VPP, and VNN supply voltages; however, analog
switch inputs must be unconnected, or satisfy VNN ≤
(VCOM_, VNO_) ≤ VPP during power-up and power-down.
Bypass VDD, VNN, and VPP to GND with a 0.1µF ceramic
capacitor as close to the device as possible.
