1 GENERAL DESCRIPTION The is a high voltage, CMOS analog IC configured as three single-pole/double-throw (SPDT) switches. This CMOS device can operate from ±1.8V to ±5.5V dual power supplies or from +3.6V to +11V single supplies. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 10nA at +25. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V or dual ±5V supplies. is available in Green SOIC-16, SSOP-16, TSSOP-16 and TQFN L packages. It operates over an ambient temperature range of -40 to +85.

RECOMMENDED OPERATING CONDITIONS Operating Temperature Range to +85 OVERSTRESS CAUTION Stresses beyond those listed may cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational section of the specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. DISCLAIMER reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time. ESD SENSITIVITY CAUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 2

11 APPLICATION INFORMATION Power-Supply Considerations Overview The construction is typical of most CMOS analog switch. It has three supply pins:,, and GND. and are used to drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD protection diodes are internally connected between each analog-signal pin and both and. If any analog signal exceeds or, one of these diodes will conduct. During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from or. Virtually all the analog leakage current comes from the ESD diodes. 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 means their leakages will vary as the signal varies. The difference in the two diode leakages to the and pins constitutes 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 either the same or opposite polarity. There is no connection between the analog-signal paths and GND. and GND power the internal logic and logic-level translators, and set the input logic limits. The logic-level translators convert the logic levels into switched and signals to drive the gates of the analog signals. This drive signal is the only connection between the logic supplies and signals and the analog supplies. and have ESD-protection diodes to GND. Bipolar Supplies This device operates with bipolar supplies between ±1.8V and ±5.5V. The and supplies need not be symmetrical, but their sum cannot exceed the +13.2V absolute maximum rating. Over-Voltage Protection Proper power-supply sequencing is recommended for the CMOS device. 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 and analog signals. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for over-voltage protection (Figure 1). Adding diodes reduces the analog-signal range to one diode drop below and one diode drop above, but does not affect the device s low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between and should not exceed 13.2V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground. * X,Y,Z VCC D1 EXTERNAL BLOCKING DIODE * * * X_,Y_,Z_ D2 EXTERNAL BLOCKING DIODE *INTERNAL PROTECTION DIODES Figure 1. Over-Voltage Protection Using External Blocking Diodes Single Supply This device operates from a single supply between +3.6V and +11V when is connected to GND. All of the bipolar precautions must be observed. At room temperature, it actually works with a single supply near or below +2.5V, although as supply voltage decreases, switch on-resistance and switching times become very high. 11
