Supertex HV2631 and HV2731: 16-channel analog switches target medical-ultrasound applications

Targeting medical- and nondestructive-testing applications, the high-voltage, 16-channel HV2631 and HV2731 analog switches provide high-resolution imaging for medical-ultrasound-diagnostic-imaging equipment. The units are available as two sets of eight SPST (single-pole/single-throw) analog switches; both ICs outputs provide a 22Ω typical on-resistance. The HV2731 features integrated bleed resistors for discharging residual dc voltages and reducing erroneous signals. All parts comply with “green” and ROHS (restriction-of-hazardous-substances) initiatives. Available in LQFP-48 packages, the HV2631FG-G and HV2731FG-G cost $14.75 and $14.95 (1000), respectively.
