►Low parasitic capacitances
►DC to 50MHz small signal frequency response
►-60dB typical output off isolation at 5.0MHz
►CMOS logic circuitry for low power
►Excellent noise immunity
►On-chip shift register, latch and clear logic circuitry
►Flexible high voltage supplies
Applications
Medical ultrasound imaging
Piezoelectric transducer drivers
General Description
This device is a low charge injection, 8-channel, high-voltage
analog switch integrated circuit (IC) intended for use in appli-
cations requiring high voltage switching controlled by low volt-
age control signals, such as ultrasound imaging and printers.
Input data is shifted into an 8-bit shift register which can then
be retained in an 8-bit latch. To reduce any possible clock
feed-through noise, Latch Enable Bar (LE) should be left high
until all bits are clocked in. Using HVCMOS® technology, this
switch combines high voltage bilateral DMOS switches and
low power CMOS logic to provide efficient control of high volt-
age analog signals.
These ICs are suitable for various combinations of high volt-
age supplies, e.g., VPP/VNN : +50V/-150V, or +100V/-100V.
