HV2301
Initial Release
General Description
The Supertex HV2301 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 control signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. The built-in bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. The HV2301 is an enhanced version of the HV232. Input data is shifted 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. The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.
Applications
Medical ultrasound imaging NDT metal flaw detection Piezoelectric transducer drivers Inkjet printer heads Optical MEMS modules

Notes: 1. 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 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.
