The MAX4686/MAX4687 MAX4686/MAX4687 are single-pole/single-throw (SPST) analog switches, and the MAX4688 MAX4688 is a single-pole/double-throw (SPDT) analog switch. The MAX4686 MAX4686 is a normally open (NO) switch, and the MAX4687 MAX4687 is a normally closed (NC) switch. The MAX4688 MAX4688 has one normally open (NO) switch and one normally closed (NC) switch. When powered from a 3V supply these devices feature 2.5 (max) RON, with 0.4 (max) RON matching and 1 (max) flatness. The MAX4686/MAX4687/MAX4688 MAX4686/MAX4687/MAX4688 offer fast switching speeds (tON = 30ns max, tOFF = 12ns max). The MAX4688 MAX4688 offers break-before-make action. The digital logic inputs are 1.8V logic compatible from a +2.7V to +3.3V supply. The MAX4686/MAX4687/ MAX4686/MAX4687/ MAX4688 MAX4688 are available in the chip-scale package (UCSPTM), significantly reducing the required PC board area. The chip occupies only a 1.50mm x 1.02mm area. The 3 x 2 array of solder bumps are spaced with a 0.5mm bump pitch.

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 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges.

Driving IN rail-to-rail minimizes power consumption. Logic inputs accept up to +5.5V regardless of supply voltage. Analog Signal Levels Vg GND Figure 1. Overvoltage Protection Using External Blocking Diodes Analog signals that range over the entire supply voltage (V+ to GND) are passed with very little change in R ON (see Typical Operating Characteristics). The switches are bidirectional, so the NO, NC, and COM pins are both inputs or outputs. Power-Supply Sequencing and Overvoltage Protection CAUTION: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to devices. _ 5 MAX4686/MAX4687/MAX4688 MAX4686/MAX4687/MAX4688 Typical Operating Characteristics (continued) (TA = +25°C, unless otherwise noted.) MAX4686/MAX4687/MAX4688 MAX4686/MAX4687/MAX4688 2.5, Low-Voltage, SPST/SPDT Analog Switches in UCSP Package Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to
