HV2303

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.

The Supertex HV2303 is a low charge injection 8-channel high voltage analog switch integrated circuit (IC) with bleed resistors.

The device HV2303 can be used in applications requiring high voltage switching controlled by low voltage signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers.

The bleed resistors of HV2303 eliminate voltage built up on capacitive loads such as piezoelectric transducers.

About HV2303,data is input into an 8-bit shift register that can then be retained in an 8-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 is clocked in during the rising edge of the clock.

Using HVCMOS technology, this device HV2303 combines high voltage bilateral DMOS switches and low power CMOS logic to provide effi cient control of high voltage analog signals.

The device HV2303 is suitable for various combinations of high voltage supplies, e.g., V_PP/V_NN: +40V/-140V, +90V/-90V, and +140V/-40V.
