Supertex inc. HV20822 16-Channel, High Voltage Analog Switch Features General Description HVCMOS technology for high performance The Supertex HV20822 is a 220V, 16-channel, high- 220V operating conditions voltage analog switch integrated circuit (IC) configured as Output on-resistance typically 22 2 sets of 8 single-pole single-throw analog switches. It is intended for use in applications requiring high voltage 5.0 and 12.0V CMOS logic compatibility switching controlled by low voltage control signals such Very low quiescent current consumption (-10A) as ultrasound imaging and printers. -45dB min off isolation at 7.5MHz Low parasitic capacitance The 2 sets of 8 analog switches are controlled by 2 input Excellent noise immunity logic controls, D 1 and D 2. A logic high on D 1 will turn IN IN IN Flexible high voltage supplies On switches 0 to 7 and a logic high on D 2 will turn On IN switches 8 to 15.
