9-88; Rev ; /7 25Ω SPST Analog Switches in SOT23-6 General Description The are dual-supply single-pole/single-throw (SPST) switches. On-resistance is 25Ω max and flat (2Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. Off-leakage current is only na max at +25. They conduct analog or digital signals equally well in either direction. The primary application areas are in the switching and routing of signals in telecommunications and test equipment. The are single SPST analog switches. The has one normally closed (N) switch, and the has one normally open (NO) switch. These devices operate from a single +9V to +36V supply or from dual ±4.5V to ±2V supplies. The are available in tiny 6-pin SOT23 packages.

Applications Information Overvoltage Protection Proper power-supply sequencing is recommended for all MOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence on first, then, followed by the logic inputs, NO, N, or OM. If power-supply sequencing is not possible, add two small signal diodes (D, D2) in series with supply pins (Figure ). Adding diodes reduces the analog signal range to one diode drop below and one diode drop above, but does not affect the devices low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between and should not exceed 44V. These protection diodes are not recommended when using a single supply. Off-Isolation at High Frequencies In 5Ω systems, the high-frequency on-response of these parts extends from D to above 3MHz, with a typical loss of -2dB. When the switch is turned off, however, it behaves like a capacitor, and off-isolation decreases with increasing frequency. This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical. The graphs shown in the Typical Operating haracteristics were taken using a 5Ω source and load connected with BN connectors. V g NO D2 D OM Figure.
