Description

HV209 is a 200V low charge injection 12-channel high voltage analog switch configured as 6 SPDT analog switches intended for medical ultrasound applications. Bleed resistors are integrated on the output switches to eliminate charge built up on the piezo electric transducers.The bleed resistors are at a nominal value of 35kO. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. The outputs are configured as single-pole double- throw analog switches. Data is shifted into a 6-bit shift register using an external clock. The LE latches the shift register data into the individual switch latches. A logic HI connects a switch common YX to SWX. A logic LOW connects YX to SWX. A logic HI in CL resets all switches to SWX simultaneously.
