detailed description the max4699/max4701 are low-voltage cmos analog switches that operate from a single +1.8v to +5.5v power supply. the max4702 requires an additional logic supply that allows for setting lower logic thresh- olds. the max4699/max4701 are double-pole/double- throw (dpdt) devices. the max4702 is a quad single-pole/double-throw (spdt) device. these devices feature a break-before-make switching, fast switching speeds (with v+ = 5v: t on = 18ns max, t off = 9ns max and with v+ = 3v: t on = 35ns, t off = 20) and rail-to-rail signal handling. a logic input on the max4702 allows for logic thresholds as low as 1.0v. applications information analog signal levels analog signals that range over the entire supply voltage (v+ to gnd) can be passed with very little change in on- resistance (see typical operating characteristics ). the switches are bidirectional, so the no, nc, and com pins can be used as either inputs or outputs. _______________________________________________________________________________________ 7 max4699/max4701/max4702 low-voltage, dual dpdt/quad spdt analog switches in qfn pin description tqfn-ep pin tssop pin max4699/ max4701 max4702 max4701 max4702 name function 1 1 3 3 nc1 analog switch 1normally closed terminal 2 4 in digital control input switch 1, 2, 3, and 4 2 4 in1, in2 digital control input switch 1 and 2 3 3 5 5 no2 analog switch 2normally open terminal 4 4 6 6 com2 analog switch 2common terminal 5 5 7 7 nc2 analog switch 2normally closed terminal 6 6 8 8 gnd ground 7 7 9 9 no3 analog switch 3normally open terminal 8 8 10 10 com3 analog switch 3common terminal 9 9 11 11 nc3 analog switch 3normally closed terminal 10 12 v l logic power-supply input 10 12 in3, in4 digital control input switch 3 and 4 11 11 13 13 no4 analog switch 4normally open terminal 12 12 14 14 com4 analog switch 4common terminal 13 13 15 15 nc4 analog switch 4normally closed terminal 14 14 16 16 v+ positive supply voltage input 15 15 1 1 no1 analog switch 1normally open terminal 16 16 2 2 com1 analog switch 1common terminal ep exposed pad (tqfn only). connect ep to gnd. positive supply com no d2 d1 gnd v g v+ max4699 max4701 max4702 figure 1. overvoltage protection using two external blocking diodes
max4699/max4701/max4702 power-supply sequencing and overvoltage protection caution: do not exceed the absolute maximum rat- ings because stresses beyond the listed ratings may cause permanent damage to the devices. proper power-supply sequencing is recommended for all cmos devices. always apply v+ before applying analog signals, especially if the analog signal is not cur- rent limited. if this sequencing is not possible, and if the analog inputs are not current limited to <20ma, add a small-signal diode (d1) as shown in figure 1. if the ana- log signal can dip below gnd, add d2. adding protec- tion diodes reduces the analog range to a diode drop (about 0.7v) below v+ (for d1), and a diode drop above ground (for d2). on-resistance increases slightly at low supply voltages. maximum supply voltage (v+) must not exceed +6v. adding protection diode d2 causes the logic threshold to be shifted relative to gnd. ttl compatibility is not guaranteed when d2 is added. protection diodes d1 and d2 also protect against some overvoltage situations. with figure 1? circuit, if the sup- ply voltage is below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result. v l logic input (max4702) the max4702 features a v l logic input that allows for lower logic input thresholds down to 1.0v min for v ih in the quad spdt configuration. power-up v l after v+ has been powered with a minimum of 1.5v to ensure proper operation of the device. low-voltage, dual dpdt/quad spdt analog switches in qfn 8 _______________________________________________________________________________________ t r < 5ns t f < 5ns 50% v il logic input r l 300 com_ gnd in_ c l includes fixture and stray capacitance. v out = v n_ ( r l ) r l + r on v n_ v ih t off 0 no_ or nc_ 0.9 x v 0ut 0.9 x v out t on v out switch output logic input logic input waveforms inverted for switches that have the opposite logic sense. v+ c l 35pf v+ v out max4699 max4701 max4702 figure 2. switching time 50% v ih v il logic input v out 0.9 x v out t d logic input r l 300 gnd c l includes fixture and stray capacitance. no_ in_ nc_ v out v+ v+ c l 35pf v n_ com_ max4699 max4701 max4702 figure 3. break-before-make interval test circuits/timing diagrams
