General Description
The MAX4677/MAX4678/MAX4679 quad analog switches feature 1.6 max on-resistance (RON) when operating from a dual 5V supply. RON is matched between channels to 0.3 max and is flat (0.4 max) over the specified signal range. Each switch can handle Rail-toRail(R) analog signals. Off-leakage current is 0.1nA at +25C. These switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automated test equipment. They have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4677 has four normally closed (NC) switches, and the MAX4678 has four normally open (NO) switches. The MAX4679 has two NC and two NO switches and features guaranteed break-before-make switching. The MAX4677/MAX4678/MAX4679 operate from either a single +2.7V to +11V or dual 2.7V to 5.5V supplies, making them ideal for use in digital card applications and single-ended 75 systems. These devices feature a separate logic supply input that operates from +2.7V to V+, allowing independent logic and analog supplies. o On-Resistance 1.6 max o On-Resistance Flatness 0.4 max o On-Resistance Matching 0.3 max o Dual 2.7V to 5.5V or Single +2.7V to +11V Supply Range o TTL/CMOS-Logic Compatible o Crosstalk -84dB at 1MHz o Off-Isolation -65dB at 1MHz o -3dB Bandwidth: 66MHz o Rail-to-Rail Signal Range

Note 1: Signals on NC_, NO_, COM_, or IN_ 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.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: RON = RON(MAX) - RON(MIN). Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 5: Leakage parameters are 100% tested at maximum-rated hot operating temperature and the highest supply voltage, and guaranteed by correlation at +25C.

___________Applications Information
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-, then VL followed by the logic inputs, NO_, NC_, or COM. If proper power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins, and a Schottky diode between V+ and VL 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 V- should not exceed 11V. Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ supply to other components. A 0.1F capacitor connected from V+ to GND is adequate for most applications.
