Please use HV20220 for all new designs. ■ Low charge injection 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 (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. ■ Very low quiescent power dissipation – 10µA ■ Output On-resistance typically 22 ohms ■ Low parasitic capacitances ■ DC to 10MHz analog signal frequency ■ -50dB typical output off isolation at 5MHz ■ CMOS logic circuitry for low power ■ Excellent noise immunity ■ On-chip shift register and latch logic circuitry ■ Flexible high voltage supplies ■ Surface mount package available Absolute Maximum Ratings* VDD logic power supply voltage VPP - VNN supply voltage -0.5V to +18V 174V VPP positive high voltage supply -0.5V to +160V VNN negative high voltage supply +0.5V to -160V Logic input voltages -0.5V to VDD +0.3V Analog signal range VNN to VPP Peak analog signal current/channel Storage temperature Power dissipation 3.0A -65°C to +150°C 1.2W * Absolute Maximum Ratings are those values beyond which damage to the device may occur.

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 clockng has no effect on the switch states if LE is H. – E T E L – OBSO HV21716/HV21816 Typical Performance Curves RON vs. Ambient Temp TA VDD = 15V & VPP/VNN = ±80V 40 RON vs. VPP/VNN VDD = 15V 50 35 RON (ohms) @ 5mA RON (ohms) 30 25 ISW = 5mA 20 15 10 40 30 TA = 125°C TA = 85°C 20 TA = 25°C TA = 0°C TA = -45°C 5 0 -55 -25 10 VPP 0 20 40 60 80 100 120 140 160 VNN -160 -140 -120 -100 -80 -60 -40 -20 0 0 25 50 75 100 125 150 Ambient Temp TA (°C) Switch Current vs. Switch Voltage Drop VDD = 15V & VPP/VNN = ±80V 400 IPP/INN vs. Output Switching Frequency VDD = 15V & VPP/VNN = ±80V 40 TA = 0°C TA = 25°C 200 ISWITCH (mA) IPP/INN Average Current (mA) 300 100 TA = 70°C 0 -100 -200 -300 -4000 200 -4 -3 -2 -1 0 1 VSWITCH (volts) 2 3 TA = 70°C TA = 25°C 20 TA = -55°C 10 0 4 Junction Temp Tj vs. Switch Peak Current VSIG Freq = 10KHz & Duty Cycle = 0.1% VDD = 15V & VPP/VNN = ±80V 275 175 0 100 200 300 HV Output Switching Freq (KHz) 400 TDO vs. Ambient Temp TA VPP/VNN = ±80V 250 TA = 75°C 150 225 VDD = 10V 125 200 TDO (ns) Junction Temp Tj (°C) TA = 125°C 30 100 75 TA = 25°C 50 175 150 125 25 VDD = 15V 100 0 75 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 Switch Peak Current (A) -50 -25 0 25 50 75 Ambient Temp TA (°C) 13-71 100 125 13 13 HV21716/HV21816 – E T E L O S B O – Typical Performance Curves 40 TWLE vs. Ambient Temp VPP/VNN = ±80V 110 36 100 32 90 28 TSD (ns) TWLE (ns) VDD = 10V 24 20 16 80 70 50 40 8 TH vs. Ambient Temp VPP/VNN = ±80V 16 14 16 12 VDD = 10V TSU (ns) TH (ns) -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) 17 14 13 12 TSU vs. Ambient Temp VPP/VNN = ±80V VDD = 10V 10 8 VDD = 15V 6 VDD = 15V 4 11 2 10 0 -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) 800 VDD = 15V 30 -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) 15 VDD = 10V 60 VDD = 15V 12 18 TSD vs. Ambient Temp VPP/VNN = ±80V -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) TON vs. Ambient Temp VPP/VNN = ±80V 2.5 TOFF vs. Ambient Temp VPP/VNN = ±80V 700 VDD = 10V 2.0 500 400 TOFF (ns) TON (ns) 600 VDD = 15V 300 200 VDD = 10V VDD = 15V 1.5 1 100 0 0 -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) -50 -25 0 25 50 75 100 125 Ambient Temp TA (°C) 13-72 HV21716/HV21816 Typical Performance Curves Off Isolation vs Signal Voltage Frequency VDD = 15V, VPP/VNN = ±80V -120 5 -100 Off Isolation (db) 6 4 3 -80 -60 2 -40 1 -20 10K 100K 1M 10K 10M 100K 1M 10M Signal Voltage Frequency (Hz) CLK Frequency (Hz) Crosstalk vs Analog Signal Frequency VDD = 15V, VPP/VNN = ±80V -100 -90 Crosstalk (db) I DD Current (mA) I DD vs CLK Frequency VDD = 15V, VPP/VNN = ±80V, TA = 0°C to 70°C -80 70 ° C -70 0° C -60 -50 100K 1M 10M 100M Analog Signal Frequency (Hz) – E T E L O S B O – 13 13 13-73 HV21716/HV21816 Pin Configurations Package Outlines 28-Pin J-Lead Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Function SW3 SW3 SW2 SW2 N/C N/C SW1 SW1 SW0 SW0 VPP VNN GND VDD 25 Pin 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Function N/C DIN CLK LE DOUT SW7 SW7 SW6 SW6 N/C SW5 SW5 SW4 SW4 24 23 22 21 20 26 18 27 17 28 16 1 15 2 14 3 13 4 12 5 6 7 8 9 10 top view 28-pin J-Lead Package – E T E L O S B O – 13-74 19 11 HV2216 8-Channel High Voltage Analog Switch Ordering Information Package Options VPP – VNN 28-pin plastic DIP 28-lead plastic chip carrier Die 160V HV2216P HV2216PJ HV2216X Features General Description ® HVCMOS technology for high performance Not recommended for new designs.
