Supertex inc. HV20822 16-Channel, High Voltage Analog Switch Features General Description ►► 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 The Supertex HV20822 is a 220V, 16-channel, highvoltage 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. ►► Medical ultrasound imaging ►► Piezoelectric transducer drivers Block Diagram VDD DIN1 Latch 1 Level Translator 1 SW0 SW0 SW7 SW7 DIN2 LE Latch 2 Level Translator 2 SW8 SW8 GND VPP VNN SW15 SW15 Doc.# DSFP-HV20822 C071613 Supertex inc. www.supertex.com HV20822 Pin Configuration Ordering Information Part Number Package Option Packing HV20820FG-G 48-Lead LQFP 250/Tray HV20820FG-G M931 48-Lead LQFP 1000/Reel 1 48 -G denotes a lead (Pb)-free / RoHS compliant package Absolute Maximum Ratings Parameter Value VDD Logic power supply voltage 48-Lead LQFP -0.5V to +15V VPP - VNN Supply voltage (top view) +225V VPP Positive high voltage supply -0.5V to VNN +225V VNN Negative high voltage supply Logic input voltages Product Marking +0.5V to -225V Top Marking -0.5V to VDD +0.3V VSIG Analog signal range YYWW VNN to VPP Peak analog signal current/channel Storage temperature HV20822FG 3.0A Bottom Marking -65°C to +150°C Power dissipation 1.0W Absolute Maximum Ratings are those values beyond which damage to the device may occur.
