HV219 200V Low Charge Injection 8-Channel High Voltage Analog Switch Features General Description HVCMOS technology for high performance The Supertex HV219 is a low switch resistance, low charge injection, 8-channel, 200V, analog switch integrated circuit (IC) Very low quiescent power dissipation (-10A) intended primarily for medical ultrasound imaging. The device can Output on-resistance typically 11 also be used for NDE (non-destructive evaluation) applications. The Low parasitic capacitance HV219 is a lower switch resistance, 11 versus 22, version of the DC to 50MHz small signal frequency response Supertex HV20220 device. The lower switch resistance will help -60dB typical off-isolation at 5.0MHz reduce insertion loss. It has the same pin configuration as that of the CMOS logic circuitry for low power Supertex HV20220PJ and the HV20220FG. Excellent noise immunity Serial shift register logic control with latches The device is manufactured using Supertexs HVCMOS (high Flexible operating supply voltages voltage CMOS) technology with high voltage bilateral DMOS Surface mount packages structures for the outputs and low voltage CMOS logic for the input control. The outputs are configured as eight independent single Applications pole single throw 11 analog switches. The input logic is an 8-bit serial to parallel shift register followed by an 8-bit parallel latch. The Medical ultrasound imaging switch states are determined by the data in the latch. Logic high will Non-destructive evaluation correspond to a closed switch and logic low as an opened switch. The HV219 is designed to operate on various combinations of high voltage supplies. For example the V and V supplies can be: PP NN +40V/-160V, +100V/-100V, or +160V/-40V. This allows the user to maximize the signal voltage for uni-polar negative, bi-polar, or uni- polar positive.
