Description  
Processed with BCDMOS on SOI (Silicon On  
The CPC7220 is a low charge injection 8-channel  
high-voltage analog switch integrated circuit (IC) for  
use in applications requiring high voltage switching.  
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  
DC to 10MHz Analog Signal Frequency  
-60dB Minimum Output-Off Isolation at 5MHz  
Low Quiescent Power Dissipation (< 1A typical)  
Output On-Resistance Typically 20  
TTL I/O's 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.  
Adjustable High Voltage Supplies  
Surface Mount Package  
Applications  
Ultrasound Imaging  
Printers  
Industrial Controls and Measurement  
Piezoelectric Transducer Drivers  
Because the CPC7220 is capable of switching high  
load voltages and has a flexible load voltage range,  
e.g. V /V : +40V/-160V or +100V/-100V, it is well  
PP NN  
suited for many medical and industrial applications  
such as medical ultrasound imaging, printers, and  
industrial measurement equipment.

Construction of the high voltage switches using IXYS  
Integrated Circuits Division's reliable BCDMOS  
process technology on SOI (Silicon On Insulator)  
allow the switches to be organized as solid state  
switches with direct gate drive.
