Description: The Supertex HV2203 is a low charge injection 8-channel high voltage analog switch integrated circuit ...
The Supertex HV2203 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 signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers.
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 effi cient control of high voltage analog signals.
The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-120V, +80V/-80V, and +120V/-40V.
