name max4541?ax4544 low-voltage, single-supply dual spst/spdt analog switches 6 _______________________________________________________________________________________ applications information logic levels the max4541?ax4544 are ttl compatible whenpowered from a single +5v supply. when powered from other supply voltages, ttl compatibility is guar- anteed and the logic inputs can be driven rail-to-rail. for example, with a +12v supply, in1 and in2 can be driven low to 0 and high to 12v. with a +3.3v supply, in1 and in2 should be driven low to 0 and high to 3.3v. driving in1 and in2 rail-to-rail minimizes power con- sumption. analog signal levels analog signals that range over the entire supply voltage(v+ to gnd) can be switched with very little change in on-resistance over the entire voltage range (see the typical operating characteristics ). all the switches are bidirectional, so the no_, nc_, and com_ pins can beused as either inputs or outputs. pin description positive supply com no d2 d1 gnd v g v+ figure 1. overvoltage protection using two external blockingdiodes digital control input 1 7 2 analog switch 2?ommon 6 6 analog switch 2?ormally open 5 ground?egative supply input 4 4 pin digital control input 2 3 3 analog switch 1?ommon 2 positive supply voltage input analog switch 1?ormally open 1 1 function 8 8 7 not connected (open circuit) analog switch?ormally closed analog switch?ormally open analog switch 2?ormally closed 5 analog switch 1?ormally closed digital control input 2 6 4 3 8 7 1 5 8 4 6 3 2 7 1 5 7 4 6 3 8 1 2 5 in1 com2 no2 gnd in2 com1 no1 name v+ n.c. nc no nc2 nc1 in analog switch?ommon com 8 4 5 6 3 1 2 7 4 8 5, 6 3 1 7 3 2 4 6 1 2 5 max4543 dip/so/ max/ tdfn max4541 dip/so/ max/ tdfn sot23-8 dip/so/ max/ tdfn max4542 sot23-8 sot23-8 dip/so/ max/ tdfn max4544 sot23-6 exposed pad. connect ep to v+. ep ep ep ep ep downloaded from: http:///
power-supply sequencing and overvoltage protection do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause perma- nent damage to the devices. proper power-supply sequencing is recommended for all cmos devices. always apply v+ before applying analog signals or logic inputs, especially if the analog or logic signals are not current limited. if this sequenc- ing is not possible, and if the analog or logic inputs are not current limited to < 10ma, add a small-signal diode (d1) as shown in figure 1. if the analog signal can dip below gnd, add d2. adding protection diodes reduces the analog signal range to a diode drop (about 0.7v) below v+ (for d1), and to a diode drop above ground (for d2). leakage is unaffected by adding the diodes. on-resistance increases by a small amount at low supply voltages. maximum supply voltage (v+) must not exceed 13v. adding protection diodes causes the logic thresholdsto be shifted relative to the power-supply rails. this can be significant when low supply voltages (+5v or less) are used. with a +5v supply, ttl compatibility is not guaranteed when protection diodes are added. driving in1 and in2 all the way to the supply rails (i.e., to a diode drop higher than the v+ pin, or to a diode drop lower than the gnd pin) is always acceptable. protection diodes d1 and d2 also protect against some overvoltage situations. with figure 1? circuit, if the supply voltage is below the absolute maximum rat- ing, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. max4541?ax4544 low-voltage, single-supply dual spst/spdt analog switches _______________________________________________________________________________________ 7 t r < 20ns t f < 20ns 50% 0 logic input r l 1k com gnd c l includes fixture and stray capacitance. v out = v com ( r l ) r l + r on switch input in +3v t off 0 noor nc switchoutput 0.9 x v 0ut 0.9 x v out t on v out switch output logic input logic input waveforms inverted for switchesthat have the opposite logic sense. v+ c l 35pf v+ v out 0v max4541 max4542 max4543 max4544 figure 2. switching time test circuits/timing diagrams downloaded from: http:///
