general description the max398/max399 precision, monolithic, cmos ana- log multiplexers (muxes) offer low on-resistance (less than 100 ), which is matched to within 6 between channels and remains flat over the specified analog sig- nal range (11 max). they also offer low leakage over temperature (no off-leakage current less than 2.5na at +85?) and fast switching speeds (transition time less than 250ns). the max398 is an 8-channel device, and the max399 is a dual 4-channel device. the max398/max399 are fabricated with maxim? low- voltage silicon-gate process. design improvements yield extremely low charge injection (less than 5pc) and guarantee electrostatic discharge protection (esd) greater than 2000v. these muxes operate with a single +3v to +15v supply or bipolar ?v to ?v supplies, while retaining cmos-logic input compatibility and fast switching. cmos inputs pro- vide reduced input loading. the max398/max399 are pin compatible with the industry-standard dg408, dg409, dg508a, and dg509a. applications sample-and-hold circuits automatic test equipment heads-up displays guidance and control systems military radios communications systems battery-operated systems pbx, pabx audio signal routing low-voltage data-acquisition systems features ? pin compatible with industry-standard dg408/dg409/dg508a/dg509a ? guaranteed on-resistance match between channels (< 6 ) ? low on-resistance (< 100 ) ? guaranteed flat on-resistance over signal range (< 11 ) ? guaranteed low charge injection (< 5pc) ? no off-leakage current < 1na at +85? ? com off-leakage current < 2.5na at +85? ? esd protection > 2000v ? +3v to +15v single-supply operation ?v to ?v bipolar-supply operation ? low power consumption (< 300?) ? rail-to-rail signal handling ? ttl/cmos-logic compatible max398/max399 precision, 8-channel/dual 4-channel, low-voltage, cmos analog multiplexers ________________________________________________________________ maxim integrated products 1 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 a1 a2 gnd v+ n01 v- en a0 top view max398 no5 no6 no7 no8 com n04 n03 n02 dip/so/qsop qfn 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 a1 gnd v+ no1b n01a v- en a0 max399 no2b no3b no4b comb coma n04a n03a n02a dip/so/qsop en a0 a1 gnd n04a coma comb n04b n01a v- n02a n03a n01b v+ n02b n03b 16 15 14 12 11 10 1 2 3 9 4 13 5678 max399 qfn en a0 a1 a2 n04 com n08 n07 n01 v- n02 n03 v+ gnd n05 n06 16 15 14 12 11 10 1 2 3 9 4 13 5678 max398 pin configurations 19-0299; rev. 5; 1/07 ordering information for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin- package pkg code max398 cge 0 c to +70 c 16 qfn-ep* g1655-3 max398cee 0 c to +70 c 16 qsop e16-1 max398cse 0 c to +70 c 16 narrow s16-1 max398cpe 0 c to +70 c 16 plastic p16-1 max398c/d 0 c to +70 c dice** max398ege -40 c to + 85 c 16 qfn-ep* g1655-3 max398eee -40 c to + 85 c 16 qsop e16-1 max398ese -40 c to + 85 c 16 narrow s16-1 max398epe -40 c to + 85 c 16 plastic p16-1 max398eje -40 c to + 85 c 16 cerdip j16-1 max398mje -55 c to +125 c 16 cerdip j16-1 ordering information continued at end of data sheet. * ep = exposed pad. ** contact factory for dice specifications.

max398/max399 applications information operation with supply voltages other than 5v using supply voltages less than ?v reduces the analog signal range. the max398/max399 muxes operate with ?v to ?v bipolar supplies or with a +3v to +15v single supply. connect v- to gnd when operating with a single supply. both device types can also operate with unbal- anced supplies, such as +10v and -5v. the typical operating characteristics graphs show typical on-resis- tance with ?v, ?v, +3v, 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 can cause permanent damage to the devices. always sequence v+ on first, then v-, followed by the logic inputs, no, or com. if power-supply sequencing is not possible, add two small signal diodes (d1, d2) in series with supply pins for overvoltage protection (figure 1). adding diodes reduces the analog signal range to one diode drop below v+ and one diode drop above v-, but does not affect the devices?low switch resistance and low leakage characteristics. device operation is unchanged, and the difference between v+ and v- should not exceed 17v. t hese protection diodes are not recommended when using a single supply. precision, 8-channel/dual 4-channel, low-voltage, cmos analog multiplexers 8 _______________________________________________________________________________________ test circuits/timing diagrams com v- v+ no * internal protection diodes d2 d1 -5v +5v max398 max399 * * * * figure 1. overvoltage protection using external blocking diodes 50% t trans t r < 20ns t f < 20ns v out +3v 0 v no1 0 v no8 logic input v en switch output +5v v out -5v gnd v+ a1 v- a2 a0 en no1 no2?o7 no8 com +5v -5v 50 max398 300 35pf +5v v out -5v gnd v+ a0 v- a1 en no1b no1a?o4a no4b comb +5v 50 max399 300 35pf 90% 90% t trans on -5v v en v en figure 2. transition time
