8-Channel High Voltage Analog Switch with  
Built-in Bleeder Resistors  
Features  
Description  
Processed with BCDMOS on SOI (Silicon on  
The CPC7232 is a low charge injection 8-channel  
high-voltage analog switch integrated circuit (IC) for  
use in applications requiring high voltage switching.  
Bleeder resistors are incorporated into both terminals  
of each output switch. Control of the high voltage  
switching is via low voltage TTL logic level compatible  
inputs for direct connectivity to the system controller.  
Insulator)  
Flexible High Voltage Supplies up to V -V +200V  
PP NN  
Output Bleed Resistors Built into the Device  
DC to 10MHz Analog Signal Frequency  
Surface Mount Package Available  
Low Quiescent Power Dissipation (< 1μA Typical)  
Output Switch On-Resistance Typically 20Ω  
TTL I/Os for 3.3V Interface  
Switch manipulation is managed by an 8-bit serial to  
parallel shift register whose outputs are buffered and  
stored by an 8-bit transparent latch. Level shifters  
buffer the latch outputs and operate the high voltage  
switches.  
Applications  
Ultrasound Imaging  
Printers  
Because the CPC7232 is capable of switching high  
load voltages and has a flexible load voltage range,  
Industrial Controls and Measurement  
e.g. V /V : +40V/160V or +100V/100V, it is well

suited for many medical and industrial applications  
such as medical ultrasound imaging, printers, and  
industrial measurement equipment. The bleeder  
resistors enable the discharge of capacitive loads,  
such as piezoelectric transducers, connected to the  
output switches of the CPC7232.
