| HV214 250V Low Charge Injection 8-Channel High Voltage Analog Switch Features HVCMOS(R) technology for high performance Very low quiescent power dissipation -10A Low parasitic capacitances DC to 10MHz analog signal frequency -60dB typical output off isolation at 5MHz -60dB typical 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 packages General Description 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. 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 feedthrough 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(R) 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/-210V, +125V/-125V, +210V/-40V.

The eight switches operate independently. 2. Serial data is clocked in on the LH transition CLK. 3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the latch. 4. DOUT is high when switch 7 is on. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs.
