HV220/HV20220/HV20320 HV220/HV20220/HV20320 Low Charge Injection 8-Channel High Voltage Analog Switches Features General Description ❏ These devices are low charge injection 8-channel high-voltage analog switch integrated circuits (ICs) 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 feed-through noise, Latch Enable Bar (LE) should be left high until all bits are clocked in. Using HVCMOS technology, these switches combine high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ 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 Flexible high voltage supplies These ICs are suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/–150V, or +100V/–100V.B Applications ❏ ❏ Medical ultrasound imaging Piezoelectric transducer drivers LATCHES Block Diagram LEVEL SHIFTERS OUTPUT SWITCHES D LE CL SW0 D LE CL SW1 D LE CL SW2 D LE CL SW3 D LE CL SW4 D LE CL SW5 D LE CL SW6 D LE CL SW7 DIN CLK 8 BIT SHIFT REGISTER DOUT VDD LE CL V NN V PP B021706 A011705 1 HV220/HV20220/HV20320 Absolute Maximum Ratings* VDD Logic power supply voltage -0.5V to +15V VPP - VNN Supply voltage 220V VPP Positive high voltage supply -0.5V to VNN +200V VNN Negative high voltage supply +0.5V to -200V Logic input voltages -0.5V to VDD +0.3V VNN to VPP Analog Signal Range Peak analog signal current/channel Storage temperature 3.0A -65°C to +150°C Power dissipation: 28-Lead PLCC 1.2W 48-Lead TQFP 1.0W 26-Lead BCC 1.0W 25-Lead FPBGA 1.0W * 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 to 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 data in shift register 7 is high. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs.
