HV20822 16 Channel High Voltage Analog Switch Ordering Information Package Options VPP-VNN 48-lead TQFP Die 220V HV20822FG HV20822X Features General Description ❏ HVCMOS technology for high performance ❏ 220V operating conditions ❏ Output On-resistance typically 22Ω ❏ 5.0V and 12.0V CMOS logic compatibility ❏ Very low quiescent power dissipation-10µA ❏ -45dB min off isolation at 7.5MHz The Supertex HV208 is a 220V 16-channel high-voltage analog switch integrated circuit (IC) configured as 2 sets of 8 single pole single throw analog switches. It is intended for use in applications requiring high voltage switching controlled by low voltage control signals such as ultrasound imaging and printers. The 2 sets of 8 analog switches are controlled by 2 input logic controls, DIN1 and DIN2. A logic high on DIN1 will turn ON switches 0 to 7 and a logic high on DIN2 will turn ON switches 8 to 15. ❏ Low parasitic capacitance ❏ Excellent noise immunity ❏ Flexible high voltage supplies ® Absolute Maximum Ratings* VDD Logic power supply voltage -0.5V to +15V VPP - VNN Supply voltage +225V VPP Positive high voltage supply -0.5V to VNN +225V VNN Negative high voltage supply Logic input voltages +0.5V to -225V -0.5V to VDD +0.3V VSIG Analog Signal Range VNN to VPP Peak analog signal current/channel Storage temperature Power dissipation 3.0A -65°C to +150°C 48-lead TQFP 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. 06/26/01 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."
