... DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resis- tance, see the MAX328 and MAX329. The MAX338/MAX339 operate from a single +4.5V to +30V supply or from dual supplies of ±4.5V to ±20V. All control inputs (whether address or enable) are TTL compatible (+0.8V to +2.4V) over the full specified tem- perature range and over the ± ...

... Information Supply Voltages Other than 15V Using supply voltages less than ±15V will reduce the analog signal range. The MAX338/MAX339 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies such as +24V and -5V ...
