General Description
The Supertex HV2201 is a low charge injection, 8-channel,
high voltage analog switch integrated circuit (IC). The
device can be used in applications requiring high voltage
switching controlled by low voltage control signals, such as
medical ultrasound imaging, piezoelectric transducer drivers,
and printers. The HV2201 is an enhanced version of the
HV20220.
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., V
PP/VNN:
+40V/-160V, +100V/-100V,
and +160V/-40V.
