Low-Voltage, CMOS Analog Multiplexers/Switches
_______________General Description
The MAX4051/MAX4052/MAX4053 and MAX4051A/ MAX4052A/MAX4053A are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4051/A), two 4-channel multiplexers (MAX4052/A), and three single-pole/double-throw (SPDT) switches (MAX4053/A). The A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage. These CMOS devices can operate continuously with dual power supplies ranging from 2.7V to 8V or a single supply between +2.7V and +16V. Each switch can handle rail-to-rail analog signals. The off leakage current is only 0.1nA at +25C or 5nA at +85C (MAX4051A/MAX4052A/4053A). All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using 5V or a single +5V supply.

Note 1: Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Power-Supply Considerations
Overview The MAX4051/MAX4052/MAX4053 and MAX4051A/ MAX4052A/MAX4053A construction is typical of most CMOS analog switches. They have three supply pins: V+, V-, and GND. V+ and V- 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 V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes will conduct. During normal operation, these (and other) reverse-biased ESD diodes leak, forming the only current drawn from V+ or V-.
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 V+ or V- and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and V- 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.

V+ and GND power the internal logic and logic-level translators, and set both the input and output logic limits. The logic-level translators convert the logic levels into switched V+ and V- 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. V+ and V- have ESD-protection diodes to GND. The logic-level thresholds are TTL/CMOS compatible when V+ is +5V. As V+ rises, the threshold increases slightly, so when V+ reaches +12V, the threshold is about 3.1V; above the TTL-guaranteed high-level minimum of 2.8V, but still compatible with CMOS outputs.

Bipolar Supplies These devices operate with bipolar supplies between 3.0V and 8V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of +17V. Single Supply These devices operate from a single supply between +3V and +16V when V- is connected to GND. All of the bipolar precautions must be observed. At room temperature, they actually "work" with a single supply at near or below +1.7V, although as supply voltage decreases, switch on-resistance and switching times become very high.

Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs (NO) and by COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and Vshould not exceed 17V. These protection diodes are not recommended when using a single supply if signal levels must extend to ground.
High-Frequency Performance
In 50 systems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics). Above 20MHz, the on response has several minor peaks which are highly layout dependent. The problem is not turning the switch on, but turning it off. The offstate switch acts like a capacitor, and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -45dB in 50 systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off isolation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is entirely due to capacitive coupling.
