The HI-201HS device was a 2nd source of the Harris HI-201 over 30 years ago when R(on) matching was not provided in most data sheets. So, unfortunately for this no-longer available device, we do not offer R(on)matching information. NOTE: All versions of HI-201HS are no longer available. Maxim does not offer a direct replacement and none is planned in the foreseeable future.
