| HV209 12-Channel High Voltage Analog Switch Ordering Information Package Options VPP - VNN 200V 48-pin TQFP HV209FG Die HV209X Features HVCMOS technology for high performance Operating voltage of up to 200V Output On-resistance typically 22 Integrated bleed resistors on the outputs Very low quiescent power dissipation -10A Low parasitic capacitances -58dB typical output off isolation at 5MHz 5.0V to 12V CMOS logic circuitry Excellent noise immunity Flexible high voltage supplies General Description The Supertex HV209 is a 200V low charge injection 12channel high voltage analog switch configured as 6 SPDT analog switch 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 35K. 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 high connects a switch common YX to SW X. A logic low connects YX to SWX. A logic hi in CL resets all switches to SWX simultaneously. Absolute Maximum Ratings* VDD Logic power supply voltage VPP - VNN Supply voltage VPP Positive high voltage supply VNN Negative high voltage supply Logic input voltages VSIG Analog Signal Range Peak analog signal current/channel Storage temperature Power dissipation -0.5V to +15V +220V -0.5V to +200V +0.5V to -200V -0.5V to VDD +0.3V VNN to VPP 3.0A -65C to +150C 1.0W * All voltages are referenced to ground. Absolute maximum ratings are those values which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. 11/12/01 Supertex Inc. does not recommend the use of its products in life support applications and will not knowingly sell its products for use in such applications unless it receives an adequate "products liability indemnification insurance agreement."
