Analog Switches - Special Purpose FAQ

What is the function of the integrated bleed resistors?

The built-in bleed resistors eliminate voltage buildup on capacitive loads, such as piezoelectric transducers, when the switches are off.

How is data loaded into the switch control registers?

Input data is shifted into an 8-bit shift register on the rising edge of the clock and then retained in an 8-bit latch when the latch enable signal goes high.

What are the typical supply voltage configurations?

The device supports flexible high voltage supplies, including VPP/VNN combinations of +40V/-160V, +100V/-100V, and +160V/-40V.
