HV214  
Initial Release  
250V Low Charge Injection  
8-Channel High Voltage Analog Switch  
Features  
General Description  
HVCMOS® technology for high performance  
The Supertex HV214 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 control signals, such as medical ultrasound imaging,  
piezoelectric transducer drivers, inkjet printer heads and optical  
MEMS modules.  
Very low quiescent power dissipation – 10µA  
Low parasitic capacitances  
DC to 10MHz analog signal frequency  
-60dB typical output off isolation at 5MHz  
CMOS logic circuitry for low power  
Excellent noise immunity  
On-chip shift register, latch and clear logic circuitry  
Flexible high voltage supplies  
Surface mount package available  
Input data is shifted into an 8-bit shift register that can then be  
retainedinan8-bitlatch.Toreduceanypossibleclockfeedthrough  
noise, the latch enable bar should be left high until all bits are  
clockedin. Dataareclockedinduringtherisingedgeoftheclock.  
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.  
Applications  
Medical ultrasound imaging  
Piezoelectric transducer drivers  
Inkjet printer heads  
The device is suitable for various combinations of high voltage  
supplies, e.g., VPP/VNN: +40V/-210V, +125V/-125V, +210V/-40V.
