HV2303 Low Charge Injection, 8-Channel High Voltage Analog Switch with Bleed Resistors Features ► ► ► ► ► ► ► ► ► ► ► ► General Description The Supertex HV2303 is a low charge injection 8-channel high voltage analog switch integrated circuit (IC) with bleed resistors. The device can be used in applications requiring high voltage switching controlled by low voltage signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. HVCMOS technology for high performance Integrated bleed resistors on the outputs 3.3V or 5.0V CMOS input logic level 20MHz data shift clock frequency Very low quiescent power dissipation - 10µA Low parasitic capacitance DC to 10MHz analog signal frequency -60dB typical off-isolation at 5.0MHz CMOS logic circuitry for low power Excellent noise immunity Cascadable serial data register with latches Flexible operating supply voltages Data is input into an 8-bit shift register that can then be retained in an 8-bit latch. To reduce any possible clock feed-through noise, the latch enable bar should be left high until all bits are clocked in. Data is clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. Applications ► ► ► ► ► Medical ultrasound imaging NDT metal flaw detection Piezoelectric transducer drivers Inkjet printer heads Optical MEMS modules The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-140V, +90V/-90V, and +140V/-40V.

The eight switches operate independently. 2. Serial data is clocked in on the L to H transition of the 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 flow through the latch. 4. DOUT is high when data in the shift register 7 is high. 5. Shift register clocking has no effect on the switch states if LE is high. 6. The CLR clear input overrides all other inputs. 5 HV2303 Test Circuits VPP-10V VPP-10V RGND RGND PP RGND VPP VDD VNN GND PP VPP VDD VNN GND PP VPP VDD VNN GND RGND RGND RGND PP PP VPP VPP VDD VNN GND PP VDD VNN GND RGND RGND PP VPP VDD VNN GND PP 6 VPP VDD VNN GND VPP VDD VNN GND HV2303 Pin Configuration - 48-Lead LQFP (FG) Pin Configuration - 28-Lead PLCC (PJ) Pin # Pin Name Pin # Pin Name Pin # Pin Name Pin # Pin Name 1 SW5 25 VNN 1 SW3 15 NC 2 NC 26 NC 2 SW3 16 DIN 3 SW4 27 RGND 3 SW2 17 CLK 4 NC 28 GND 4 SW2 18 LE SW1 19 CLR 5 SW4 29 VDD 5 6 NC 30 NC 6 SW1 20 DOUT 7 NC 31 NC 7 SW0 21 SW7 8 SW3 32 NC 8 SW0 22 SW7 9 NC 33 DIN 9 NC 23 SW6 10 SW3 34 CLK 10 VPP 24 SW6 RGND 25 SW5 11 NC 35 LE 11 12 SW2 36 CLR 12 VNN 26 SW5 13 NC 37 DOUT 13 GND 27 SW4 14 SW2 38 NC 14 VDD 28 SW4 15 NC 39 SW7 16 SW1 40 NC 17 NC 41 SW7 18 SW1 42 NC 19 NC 43 SW6 20 SW0 44 NC 21 NC 45 SW6 22 SW0 46 NC 23 NC 47 SW5 24 VPP 48 NC Typical Waveforms D N+1 DN DATA IN 5 0% LE 50% DN - 1 50% 50% t WLE t SD 50% CLOCK 50% t SU th t DO DATA O UT 50% t OFF VOUT OFF (TYP ) 90% 1 0% ON CLR t ON 5 0% 5 0% t WCL 7 HV2303 48-Lead LQFP Package Outline (FG) 7x7mm body, 1.6mm height (max.), 0.50mm pitch D D1 E E1 Note 1 (Index Area D1/4 x E1/4) Gauge Plane L2 48 L 1 Seating Plane θ L1 b e Top View View B View B A A2 Seating Plane A1 Side View Note 1: A Pin 1 identifier must be located in the index area indicated.
