HV220 Datasheet | Supertex

Features HVCMOS® technology for high performance Very low quiescent power dissipation - 10µA Output on-resistance typically 22 ohms Low parasitic capacitances DC to 10MHz analog signal frequency -60d B typical output 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 General Description These devices are low charge injection 8-channel high-voltage analog switch integrated circuits (ICs) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers. 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 Bar (LE) should be left high until all bits are clocked in. Using HVCMOS technology, these switches bine high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. These ICs are suitable for various binations of high voltage supplies, e.g., VPP/VNN : +50V/- 150V, or +100V/- 100V.B Applications Medical ultrasound imaging Piezoelectric transducer drivers Block Diagram LATCHES D LE CL LEVEL SHIFTERS OUTPUT SWITCHES SW0 D LE CL CLK D LE CL SW1 SW2 8-Bit Shift Register D LE CL SW3 D LE CL SW4 D LE CL SW5 DOUT D LE CL SW6 D LE CL SW7 V NN V PP HV220/HV20220/HV20320 Ordering Information Package Options Device 28-Lead PLCC HV20220PJ HV20220PJ-G HV20320PJ HV20320PJ-G 48-Lead LQFP/TQFP (1.4mm) HV20220FG HV20220FG-G 25-Ball fp BGA HV220GA HV220GA-G - HV220 HV20220 HV20320 .. -G indicates the part is Ro HS pliant (‘Green’) Absolute Maximum Ratings Parameter VDD logic power supply voltage VPP - VNN supply voltage VPP positive high voltage supply VNN negative high voltage supply Logic input voltages Analog signal range Peak analog signal current/channel Storage temperature...
