DESCRIPTION
Bleed resistors are incorporated into both terminals of each output switch. Control of the high voltage switching is via low voltage CMOS logic level inputs for direct connectivity to the system controller. Switch manipulation is managed by an 16-bit serial to parallel shift register whose outputs are buffered and stored by a 16-bit transparent latch. Level shifters buffer the latch outputs and operate the high voltage switches. VPP/VNN: +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 bleed resistors enable the discharge of capacitive loads, such as piezoelectric transducers, connected to the output switches of the CPC7701.
