The 8-channel MAX338 is♦On-Resistance, <400Ωmaxdesigned to connect one of eight inputs to a common♦Transition Time, <500nsoutput by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four♦On-Resistance Match, <10Ωinputs to a common output by control of a 2-bit binary♦NO-Off Leakage Current, <20pA at +25°Caddress. Both devices can be used as either a mux or♦1.5pC Charge Injectiona demux. On-resistance is 400Ωmax, and the devicesconduct current equally well in both directions.♦Single-Supply Operation (+4.5V to +30V)These muxes feature extremely low off leakages (lessBipolar-Supply Operation (±4.5V to ±20V)than 20pA at +25°C), and extremely low on-channel♦Plug-In Upgrade for Industry-Standardleakages (less than 50pA at +25°C). The new designDG508A/DG509Aoffers guaranteed low charge injection (1.5pC typ) andelectrostatic discharge (ESD) protection greater than♦Rail-to-Rail Signal Handling2000V, per method 3015.7. These improved muxes are♦TTL/CMOS-Logic Compatiblepin-compatible upgrades for the industry-standardDG508A and DG509A.

Supply Voltages Other than 15VUsing supply voltages less than ±15V will reduce theanalog signal range. The MAX338/MAX339 switchesoperate with ±4.5V to ±20V bipolar supplies or with a+4.5V to +30V single supply. Connect V- to GND whenoperating with a single supply. Both device types canalso operate with unbalanced supplies such as +24Vand -5V. The Typical Operating Characteristicsgraphsshow typical on-resistance with 20V, 15V, 10V, and 5Vsupplies. (Switching times increase by a factor of twoor more for operation at 5V.)V+NOCOMVgOvervoltage Protection

Proper power-supply sequencing is recommended forall CMOS devices. Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings may cause permanent damage to the sequence V+ on first, then V-, followed by thelogic inputs NO and COM. If power-supply sequencingis not possible, add two small signal diodes in serieswith supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to 1Vbelow V+ and 1V above V-, but does not affect thedevices’ low switch resistance and low leakage charac-teristics. Device operation is unchanged, and the differ-ence between V+ and V- should not exceed 44V.6V-Figure 1.
