The TEST pin serves two functions. On the ICL7106 it is coupled to the internally generated digital supply through
analog-to-digital converters. They differ from the Maxim ●● Hold Pin Allows Indefinite Display Hold ICL7106 and ICL7107 in that the ICL7116 and ICL7117 ●● Guaranteed First Reading Recovery from Overrange have a Hold pin, which makes it possible to hold or “freeze” a reading.
