SUTEX HV2601FG-G Low charge injection 16-channel high voltage analog switch Datasheet

HV2601
Initial Release
Low Charge Injection 16-Channel
High Voltage Analog Switch
Features
General Description
The Supertex HV2601 is a low charge injection 16-channel high
voltage analog switch integrated circuit (IC) intended for use in
applications requiring high voltage switching controlled by low
voltage control signals, such as medical ultrasound imaging and
other piezoelectric transducer drivers.
HVCMOS technology for high performance
16 Channels of high voltage analog switch
3.3V input logic level compatible
20MHz data shift clock frequency
Very low quiescent power dissipation -10µA
Low parasitic capacitance
DC to 10MHz analog signal frequency
-60dB typical off-isolation at 5MHz
CMOS logic circuitry for low power
Excellent noise immunity
Cascadable serial data register with latches
Flexible operating supply voltages
Input data is shifted into a 16-bit shift register that can then be
retained in a 16-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 are 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
Optical MEMS modules

OUTPUT SWITCH
Th 16 switches operate independently.
Serial data is clocked in on the L to H transition of the CLK.
All 16 switches go to a state retaining their latched condition at the rising edge of LE. When LE is low the shift registers data flow through the latch.
DOUT is high when data in the register 15 is high.
Shift registers clocking has no effect on the switch states if LE is high.
The CL clear input overrides all other inputs.
