High-Speed, Low-Voltage, Dual SPST CMOS Analog Switches
MAX4641/MAX4642/MAX4643 monolithic, dual, single-pole/single-throw (SPST) switches that operate from single supply ranging from +1.8V +5.5V. MAX4641/MAX4642/MAX4643 provide on-resistance (RON), matching between channels, flatness over entire analog signal range. These devices offer fast switching times less than 20ns while consuming less than 0.01µW quiescent power. MAX4641 normally open (NO) switches, MAX4642 normally closed (NC) switches. MAX4643 switch switch. three devices have 0.35nA leakage currents over entire temperature range. MAX4641/ MAX4642/MAX4643 available small 8-pin µMAX packages.

MAX4641/MAX4642/MAX4643 operate from single supply ranging from +1.8V +5.5V. devices guaranteed functional over that supply range, TTL/CMOS compatibility only valid operation using supply. voltage levels referenced
GND. Positive negative analog inputs signals accommodated shifting GND. ESD-protection diodes internally connected between each analog-signal both GND. these diodes conducts analog signal exceeds (Figure Virtually analog leakage current comes from diodes GND. Although diodes given signal identical, therefore fairly well balanced, they reverse biased differently. Each biased either analog signal. This means their leakages will vary signal varies. difference diode leakages pins constitutes analog-signal-path leakage current. analog leakage current flows between each supply terminals, other switch terminal. This both sides given switch show leakage currents same opposite polarity. There normal current path between analogsignal paths GND. also power internal logic logic-level translators. logiclevel translators convert logic level into switched signals drive analog signal gates.
