HV20220 HV20320 Low Charge Injection 8-Channel High Voltage Analog Switch Ordering Information Package Options 28-pin plastic DIP VPP – VNN 28-lead plastic chip carrier 48-lead TQFP µ-BGA Die 200V HV20220P HV20220PJ HV20220FG HV20220GA HV20220X 200V — HV20320PJ — — — Features General Description ❏ HVCMOS technology for high performance ❏ Very low quiescent power dissipation – 10µA ❏ Output On-resistance typically 22 ohms ❏ Low parasitic capacitances ❏ DC to 10MHz analog signal frequency ❏ -60dB typical output off isolation at 5MHz ❏ CMOS logic circuitry for low power ❏ Excellent noise immunity ❏ On-chip shift register, latch and clear logic circuitry This device is a low charge injection 8-channel high-voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers. Input data is shifted into an 8-bit shift register which can then be retained in an 8-bit latch. To reduce any possible clock feedthrough noise, Latch Enable Bar (LE) should be left high until all bits are clocked in. Using HVCMOS technology, this switch combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. The HV203 has the same electrical specifications as the HV202, but it is packaged in the 28 lead plastic chip carrier with the pin configuration of the Supertex HV2216PJ. ❏ Flexible high voltage supplies ❏ Surface mount package available ® This IC is suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/–150V, or +100V/–100V.

The eight switches operate independently. 2. Serial data is clocked in on the L→ H transition CLK. 3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the latch. 4. DOUT is high when switch 7 is on. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs. 7 HV20220/HV20320 Typical Performance Curves IDD vs Clock Frequency VDD = 5.0V, VPP/VNN = ±100V, TA = 0°C to 70°C Off-Isolation vs. Signal Voltage Frequency VDD = 5.0V, VPP/VNN = ±100V -80.0 3.0 Off-Isolation (dB) IDD CURRENT (mA) -75.0 TA = 70°C 2.0 1.0 -70.0 -65.0 -60.0 TA = 0°C -55.0 -50.0 0.0 10 100 1000 1.0 10000 10.0 CLK Frequency (KHz) Signal Voltage Frequency (MHz) RON vs. Ambient Temperature TA RON vs. VPP/VNN VDD = 5.0V, VPP/VNN = ±100V VDD = 5.0V 40.0 50.0 TA = 125°C ISW = 5mA 40.0 RON (ohms) @5mA RON (ohms) 30.0 20.0 ISW = 200mA 10.0 TA = 85°C 30.0 TA = 25°C 20.0 TA = 0°C 10.0 0 0 -50 -25 0 25 50 75 100 125 150 Ambient Temperature (°C) VPP 40V 60V 80V 100V 120V 140V 160V VNN -160V -140V -120V -100V -80V -60V -40V TDO vs. Ambient Temperature TA IPP/INN vs. Output Switching Frequency VPP/VNN = ±100V VDD = 5.0V, VPP/VNN = ±100V 5 100 TA = 0°C IPP/INN Average Current (mA) VDD = 5.0V TDO (ns) 80 60 VDD = 13.5V 40 20 0 TA = 25°C 4 TA = 70°C TA = 125°C 3 2 1 0 -50 -25 0 25 50 75 100 0 125 25 50 75 100 125 Output Switching Frequency (KHz) Ambient Temp TA (°C) 8 150 HV20220/HV20320 Pin Configurations HV202 28-Pin DIP Pin Function 1 SW3 2 SW3 3 SW2 4 SW2 5 SW1 6 SW1 7 SW0 8 SW0 9 N/C 10 VPP 11 N/C 12 VNN 13 GND 14 VDD Pin 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Package Outlines Function N/C DIN CLK LE CL DOUT SW7 SW7 SW6 SW6 SW5 SW5 SW4 SW4 1 28 2 27 3 26 4 25 5 24 6 23 7 22 HV202 8 21 9 20 10 19 11 18 12 17 13 16 14 15 top view 28-pin DIP HV202 28 Pin J-Lead Pin Function 1 SW3 2 SW3 3 SW2 4 SW2 5 SW1 6 SW1 7 SW0 8 SW0 9 N/C 10 VPP 11 N/C 12 VNN 13 GND 14 VDD HV203 28 Pin J-Lead Pin Function 1 SW3 2 SW3 3 SW2 4 SW2 5 SW1 6 SW1 7 SW0 8 SW0 9 VPP 10 VNN 11 N/C 12 GND 13 VDD 14 N/C Pin 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Pin 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Function N/C DIN CLK LE CL DOUT SW7 SW7 SW6 SW6 SW5 SW5 SW4 SW4 25 24 23 22 21 20 19 26 18 HV202, HV203 27 Function N/C DIN CLK LE CL DOUT SW7 SW7 SW6 SW6 SW5 SW5 SW4 SW4 17 28 16 1 15 2 14 3 13 4 12 5 6 7 8 9 10 top view 28-pin J-Lead Package 9 11 HV20220/HV20320 Pin Configurations Pin 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 Function VNN N/C N/C GND VDD N/C N/C N/C DIN CLK LE CLR DOUT N/C SW7 N/C SW7 N/C SW6 N/C SW6 N/C SW5 N/C Pin 1 HV202 Pin #1 HV202 48-Pin TQFP Pin Function 1 SW5 2 N/C 3 SW4 4 N/C 5 SW4 6 N/C 7 N/C 8 SW3 9 N/C 10 SW3 11 N/C 12 SW2 13 N/C 14 SW2 15 N/C 16 SW1 17 N/C 18 SW1 19 N/C 20 SW0 21 N/C 22 SW0 23 N/C 24 VPP Package Outlines Pin 12 top view 48-pin TQFP 10 HV20220/HV20320 HV20220GA Package Outline (µ-BGA) 5.7 ± 0.05 DIE 4.65 2.85 0.75 A1 CORNER INDEX DATUM AXIS 'Y' 0.375 0.75 A B C D E F SI HV20220GA AAAAAAA 5 ± 0.05 2.5 A B C D E F 1 2 3 4 5 6 7 DIE 4.09 7 6 5 4 3 2 1 DATUM AXIS 'X' LOT # BUMP VIEW BACK VIEW NOTES: 1.
