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.
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.
The device is suitable for various combinations of high voltage
supplies, e.g., VPP/VNN: +40V/-140V, +90V/-90V, and +140V/-40V.
