general description the max306/max307 precision, monolithic, cmos analog multiplexers (muxes) offer low on-resistance (less than 100), which is matched to within 5 between channels and remains flat over the specified analog signal range (7, max). they also offer low leakage over temperature (i no(off) less than 2.5na at +85c) and fast switching speeds (t trans less than 250ns). the max306 is a single-ended 1-of-16 device, and the max307 is a differential 2-of-8 device. the max306/max307 are fabricated with maxims improved 44v silicon-gate process. design improvements yield extremely low charge injection (less than 10pc) and guarantee electrostatic discharge (esd) protection greater than 2000v. these muxes operate with a single +5v to +30v supply, or bipolar 4.5v to 20v supplies, while retaining ttl/ cmos-logic input compatibility and fast switching. cmos inputs provide reduced input loading. these improved parts are plug-in upgrades for the industrystandard dg406, dg407, dg506a, and dg507a. applications beneits and features guaranteed on-resistance match between channels, < 5 max low on-resistance, < 100 max guaranteed flat on-resistance over specified signal range, 7 max guaranteed charge injection, < 10pc i no(off) leakage < 2.5na at +85c i com(off) leakage < 20na at +85c esd protection > 2000v plug-in upgrade for industry-standard dg406/dg407/dg506a/dg507a single-supply operation (+5v to +30v) bipolar-supply operation (4.5v to 20v) low power consumption, < 1.25mw rail-to-rail signal handling ttl/cmos-logic compatible ordering information continued at end of data sheet. *contact factory for dice specifications. 19-0270; rev 5; 3/16 sample-and-hold circuits test equipment heads-up displays guidance and control systems military radios communications systems battery-operated systems pbx, pabx audio signal routing part temp range pin-package max306 cpi 0c to +70c 28 pdip max306cwi 0c to +70c 28 wide so max306c/d 0c to +70c dice* max306epi -40c to +85c 28 pdip max306ewi -40c to +85c 28 wide so max306eqi -40c to +85c 28 plcc max306eui -40c to +85c 28 tssop max306mji -55c to +125c 28 cerdip 28 2726 25 24 23 22 21 12 3 4 5 6 7 8 comv- no8 no7 no16 n.c. n.c. v+ top view no6no5 no4 no3 no12 no13 no14 no15 2019 18 17 9 1011 12 no2 no1en a0 gnd no9 no10 no11 pdip/so/tssop max306 1615 1314 a1 a2 pin configurations/functional diagrams/truth tablescontinued at end of data sheet. a3 n.c. a2 a1 a0 en x 00 0 0 1 1 1 1 0 0 0 0 1 1 1 1 x 00 1 1 0 0 1 1 0 0 1 1 0 0 1 1 x 01 0 1 0 1 0 1 0 1 0 1 0 1 0 1 01 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 none 12 3 4 5 6 7 8 9 1011 12 13 14 15 16 max306 logic 0 v al 0.8v, logic 1 = v ah 2.4v a3 x 00 0 0 0 0 0 0 1 1 1 1 1 1 1 1 max306/max307 precision, 16-channel/dual 8-channel, high-performance, cmos analog multiplexers pin conigurations/functional diagrams/truth tables ordering information downloaded from: http:///

applications information operation with supply voltages other than 15v using supply voltages other than 15v will reduce the analog signal range. the max306/max307 switches operate with 4.5v to 20v bipolar supplies or with a +5v to +30v single supply; connect v- to gnd when operating with a single supply. also, both device types can 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 for 5v operation, up to a maximum of 10s.) overvoltage protection proper power-supply sequencing is recommended for all cmos devices. do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. always sequence v+ on first, then v-, followed by either the logic inputs, no or 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 above v+ and 1v below v-, but low switch resistance and low leakage characteristics are unaffected. device operation is unchanged, and the difference between v+ and v- should not exceed +44v. figure 1. overvoltage protection using external blocking diodes max306 pin name function 1 v+ positive supply voltage input 2, 3, 13 n.c. no connection. not internally connected. 4C11 no16Cno9 analog inputsCbidirectional 12 gnd ground 14C17 a3Ca0 address inputs 18 en enable inputs 19C26 no1Cno8 analog inputsCbidirectional 27 v- negative supply voltage input 28 com outputCbidirectional max307 pin name function 1 v+ positive supply voltage input 2 comb output bCbidirectional 3, 13, 14 n.c. no connection. not internally connected. 4C11 no8bCno1b analog inputsCbidirectional 12 gnd ground 15, 16, 17 a2, a1, a0 address inputs 18 en enable input 19C26 no1aCno8a analog inputsCbidirectional 27 v- negative supply voltage input 28 coma output aCbidirectional v g no com max306 v- v+ max306/max307 precision, 16-channel/dual 8-channel, high-performance, cmos analog multiplexers www.maximintegrated.com maxim integrated 6 pin description downloaded from: http:///
