Supertex inc. www.supertex.com Doc.# DSFP-HV232 C071613 HV232 Features ► HVCMOS® technology for high performance ► Very low quiescent power dissipation (10µA max.) ► Output on-resistance (22Ω typ.) ► Integrated bleed resistors on the outputs ► Low parasitic capacitances ► DC to 50MHz small signal frequency response ► -60dB typical output off isolation at 5.0MHz ► CMOS logic circuitry for low power ► Excellent noise immunity ► On-chip shift register, latch and clear logic circuitry ► Flexible high voltage supplies Applications ► Medical ultrasound imaging ► Piezoelectric transducer drivers Block Diagram Low Charge Injection 8-Channel High Voltage Analog Switches with Bleed Resistors General Description The Supertex HV232 is a low charge injection 8-channel, high-voltage, analog switch integrated circuit (IC) with bleed resistors. This device can be used in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers. The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. Input data is shifted into an 8-bit shift register which can then be retained in an 8-bit latch. To reduce any possible clock feed-through noise, Latch Enable (LE) should be left high until all bits are clocked in. Using HVCMOS® technology, this switch combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. This IC is suitable for various combinations of high voltage supplies, e.g., V PP/VNN: +50V/–150V, or +100V/–100V.
