MAX4781/max4782/max4783 high-speed, low-voltage, 0.7 ? cmos analog switches/multiplexers 8 _______________________________________________________________________________________ applications information power-supply considerations overview the MAX4781/max4782/max4783 construction is typical of most cmos analog switches. there are two supply inputs: v cc and gnd. v cc and gnd drive the internal cmos switches and set the limits of the analog voltage on any switch. internal reverse esd-protection diodes are connected between each analog signal input and both v cc and gnd. if any analog signal exceeds v cc or gnd, one of these diodes conducts. during normal oper- ation, these and other reverse-biased esd diodes leak, forming the only current drawn from v cc or gnd. virtually all the analog leakage current comes from the esd diodes. although the esd diodes on a given sig- nal input are identical and therefore fairly well bal- anced, they are reverse-biased differently. each diode is biased by either v cc or gnd and the analog signal. their leakages vary as the signal varies. the difference in the two diodes?leakages to v cc and gnd consti- tutes the analog-signal-path leakage current. all analog leakage current flows between each input and one of the supply terminals, not to the other switch terminal. both sides of a given switch can show leakage currents of either the same or opposite polarity. v cc and gnd power the internal logic and set the input logic limits. logic inputs have esd-protection diodes to ground. power supply the MAX4781/max4782/max4783 operate from a sin- gle supply between +1.6v and +3.6v. switch on-resis- tance increases as the supply voltage is lowered. high-frequency performance in 50 ? systems, signal response is reasonably flat up to 50mhz (see the typical operating characteristics ). above 20mhz, the on-response has several minor peaks that are highly layout dependent. in the off state, the switch acts like a capacitor and passes higher fre- quencies with less attenuation. at 10mhz, off-isolation is approximately -50db in 50 ? systems, becoming worse (approximately 20db per decade) as frequency increases. higher circuit impedance also degrades off- isolation. adjacent channel attenuation is approximate- ly 3db above that of a bare ic socket and is entirely because of capacitive coupling. pin nomenclature the MAX4781/max4782/max4783 are pin compatible with the industry-standard 74hc4051/74hc4052/ 74hc4053 and the max4617/max4618/max4619. in single-supply applications, they function identically and have identical logic diagrams, although these parts dif- fer electrically. the pin designations and logic dia- grams in this data sheet conform to the original 1972 specifications published by rca for the cd4051/ cd4052/cd4053. these designations differ from the standard maxim switch and mux designations found on other maxim data sheets such as the max4051/ max4052/max4053. designers who are more comfort- able with maxim? standard designations are advised that the pin designations and logic diagrams on the max4051/max4052/max4053 data sheet can be applied to the MAX4781/max4782/max4783.
