1 9-7; Rev ; / High-Speed, Low-Voltage, 4, General Description The is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +.V to +.V. It provides low 4 on-resistance (R ON ) as well as R ON flatness over the entire analog-signal range. The offers fast switching times of less than while euring break-before-make operation. It typically coumes only.μw of quiescent power, making it suitable for use in low-power, portable applicatio. The s features include low leakage currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. It is packaged in either a small -pin μmax or a tiny -pin SOT3.

7 N, Applicatio Information The operates from a single supply ranging from +.V to +.V. The device is guaranteed to be functional over that supply range, but TTL/CMOS compatibility is only valid for operation using a +V supply. All voltage levels are referenced to. Positive and negative DC analog inputs or AC signals can be accommodated by shifting and. ESD-protection diodes are internally connected between each analog-signal pin and both and. One of these diodes conducts if any analog signal exceeds or (Figure ). Virtually all of the analog leakage current comes from the ESD diodes to Figure. Overvoltage Protection Using External Blocking Diodes or. Although the ESD diodes on a given signal pin are identical, and therefore fairly well balanced, they are reverse biased differently. Each is biased by either or and the analog signal. This mea their leakages will vary as the signal varies. The difference in the two diode leakages to the and pi cotitutes the analog-signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no normal current path between the analogsignal paths and or. and also power the internal logic and logic-level tralators. The logiclevel tralators convert the logic level into switched and signals to drive the analog signal gates.
