HV20822
16-Channel,
High Voltage Analog Switch
Features
HVCMOS® technology for high performance
►220V operating conditions
Output on-resistance typically 22Ω
►5.0 and 12.0V CMOS logic compatibility
►Very low quiescent current consumption (-10µA)
-45dB min off isolation at 7.5MHz
Low parasitic capacitance
►Excellent noise immunity
►Flexible high voltage supplies
Applications
Medical ultrasound imaging
Piezoelectric transducer drivers
General Description
The Supertex HV20822 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.
