HV214 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 Very low quiescent power dissipation (-10A) applications requiring high voltage switching controlled by low Low parasitic capacitances voltage control signals, such as medical ultrasound imaging, DC to 50MHz small signal frequency response piezoelectric transducer drivers, inkjet printer heads and optical -60dB typical output off isolation at 5.0MHz MEMS modules. CMOS logic circuitry for low power Excellent noise immunity Input data is shifted into an 8-bit shift register that can then be On-chip shift register, latch and clear logic circuitry retained in an 8-bit latch. To reduce any possible clock feedthrough Flexible high voltage supplies noise, the latch enable bar should be left high until all bits are Surface mount packages clocked in. Data are clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage Applications bilateral DMOS switches and low power CMOS logic to provide Medical ultrasound imaging efficient control of high voltage analog signals. Non-destructive evaluation The device is suitable for various combinations of high voltage Inkjet printer heads supplies, e.g., V /V : +40V/-210V, +125V/-125V, +210V/-40V.
