_______________general description the max338/max339 are monolithic, cmos analog multiplexers (muxes). the 8-channel max338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. the dual, 4- channel max339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. both devices can be used as either a mux or a demux. on-resistance is 400 max, and the devices conduct current equally well in both directions. these muxes feature extremely low off leakages (less than 20pa at +25?), and extremely low on-channel leakages (less than 50pa at +25?). the new design offers guaranteed low charge injection (1.5pc typ) and electrostatic discharge (esd) protection greater than 2000v, per method 3015.7. these improved muxes are pin-compatible upgrades for the industry-standard 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 ?.5v to ?0v. 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 ?.5v to ?8v supply range. these parts are fabricated with maxim? 44v sili- con-gate process. ________________________applications data-acquisition systems sample-and-hold circuits test equipment heads-up displays military radios communications systems guidance and control systems pbx, pabx ____________________________features ? on-resistance, <400 max ? transition time, <500ns ? on-resistance match, <10 ? no-off leakage current, <20pa at +25? ? 1.5pc charge injection ? single-supply operation (+4.5v to +30v) bipolar-supply operation (?.5v to ?0v) ? plug-in upgrade for industry-standard dg508a/dg509a ? rail-to-rail signal handling ? ttl/cmos-logic compatible ? esd protection >2000v, per method 3015.7 ______________ordering information max338/max339 8-channel/dual 4-channel, low-leakage, cmos analog multiplexers ________________________________________________________________ maxim integrated products 1 cmos decode logic a2 a1 a0 en no8 no7 no6 no5 no4 no3 no2 no1 com v+ v- gnd max338 8-channel single-ended multiplexer 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 a1 a2 gnd v+ no1 v- en a0 top view max338 no5 no6 no7 no8 com no4 no3 no2 dip/so continued at end of data sheet. _____________________pin configurations/functional diagrams/truth tables call toll free 1-800-998-8800 for free samples or literature. 19-0272; rev 0; 8/94 part max338 cpe max338cse max338c/d 0? to +70? 0? to +70? 0? to +70? temp. range pin-package 16 plastic dip 16 narrow so dice* ordering information continued at end of data sheet. * contact factory for dice specifications. ** contact factory for availability. max338epe -40? to +85? 16 plastic dip max338ese -40? to +85? 16 narrow so MAX338EJE -40? to +85? 16 cerdip max338mje -55? to +125? 16 cerdip**

__________applications information operation with supply voltages other than 15v using supply voltages less than ?5v will reduce the analog signal range. the max338/max339 switches operate with ?.5v to ?0v 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. the typical operating characteristics graphs show typical on-resistance with 20v, 15v, 10v, and 5v supplies. (switching times increase by a factor of two or more for operation at 5v.) overvoltage protection proper power-supply sequencing is recommended for all cmos devices. do not exceed the absolute maxi- mum ratings, because stresses beyond the listed rat- ings may cause permanent damage to the devices. always sequence v+ on first, then v-, followed by the logic inputs no and com. if power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (figure 1). adding diodes reduces the analog signal range to 1v below v+ and 1v above v-, but does not affect the devices?low switch resistance and low leakage charac- teristics. device operation is unchanged, and the differ- ence between v+ and v- should not exceed 44v. max338/max339 8-channel/dual 4-channel, low-leakage, cmos analog multiplexers 6 _______________________________________________________________________________________ ______________________________________________________________pin description v g no com v- v+ figure 1. overvoltage protection using external blocking diodes pin max338 max339 name function 1, 15, 16 a0, a2, a1 address inputs a0, a1 address inputs 2 2 en enable input 3 3 v- negative supply voltage input 4? no1?o4 analog inputs?idirectional 4? no1a?o4a analog inputs?idirectional 8 com analog output?idirectional 8, 9 coma, comb analog outputs?idirectional 9?2 no8?o5 analog inputs?idirectional 10?3 no4b?o1b analog inputs?idirectional 13 14 v+ positive supply voltage input 14 15 gnd ground 1, 16
