General Description HVCMOS technology for high performance Very low quiescent power dissipation-10µA Output On-resistance typically 11Ω Low parasitic capacitance DC to 10MHz analog signal frequency -60dB typical off-isolation at 5MHz CMOS logic circuitry for low power Excellent noise immunity Serial shift register logic control with latches Flexible operating supply voltages Surface mount packages The Supertex HV219 is a low switch resistance, low charge injection 8-channel 200V analog switch integrated circuit (IC) intended primarily for medical ultrasound imaging. The device can also be used for NDE, non-destructive evaluation applications. The HV219 is a lower switch resistance, 11ohms versus 22ohms, version of the Supertex HV20220 device. The lower switch resistance will help reduce insertion loss. It has the same pin configuration as that of the Supertex HV20220PJ and the HV20220FG. The device is manufactured using Supertex’s HVCMOS (high voltage CMOS) technology with high voltage bilateral DMOS structures for the outputs and low voltage CMOS logic for the input control. The outputs are configured as eight independent single pole single throw 11 ohms analog switches. The input logic is an 8bit serial to parallel shift register followed by an 8-bit parallel latch. The switch states are determined by the data in the latch. Logic high will correspond to a closed switch and logic low as an opened switch. Applications ! ! Medical Ultrasound Imaging Non-Destructive Evaluation The HV219 is designed to operate on various combinations of high voltage supplies. For example the VPP and VNN supplies can be: +40V/-160V, +100V/-100V, or +160V/-40V. This allows the user to maximize the signal voltage for uni-polar negative, bi-polar, or unipolar positive.

This applies for applications powering GND of the IC with different voltages. Vsig must always be at or in between VPP and VNN or floating during power up/down transition. Rise and fall times of the power supplies VDD, VPP, and VNN should not be less than 1.0ms. 2) 3) Logic Truth Table Data in the 8-bit Shift Register D1 D2 D3 D4 D5 D6 D7 D0 L H L H L H L H L H L H L H X X X X Notes: 1. 2.

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