| HV20720 Dual 1 of 4 High Voltage Analog Switch Ordering Information Package Options VPP-VNN 200V 28-Lead Plastic Chip Carrier HV20720PJ Die HV20720X Features HVCMOS(R) technology for high performance Operating voltage of up 200V Very low quiescent current-10A Low parasitic capacitances Over 20MHz bandwidth -58dB typical output off isolation at 5MHz 5.0V CMOS logic circuitry Excellent noise immunity Flexible high voltage supplies General Description The Supertex HV207 is an 8-channel high-voltage analog switch integrated circuit (IC) configured as a dual 1 of 4 analog switch. The 2 sets of 4 analog switches are controlled independently with the 2 independent 1:4 decoders. The addressed switches are turned ON and the unaddressed switches are turned OFF. A logic high on the input clear pin will turn OFF all output switches regardless of the address input states. 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, 28 pin PLCC -0.5V to +7.5V +220V -0.5V to +200V +0.5V to -200V -0.5V to VDD +0.3V VNN to VPP 3.0A -65C to +150C 1.2W * 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."
