19-2008; Rev 0; 4/01 0.4, Low-Voltage, Single-Supply SPST Analog Switches in SC70 General Description The MAX4715/MAX4716 are low on-resistance, lowvoltage, single-pole/single-throw (SPST) analog switches that operate from a +1.6V to +3.6V single supply. The MAX4715 is normally open (NO), and the MAX4716 is normally closed (NC). These devices also have fast switching speeds (tON = 18ns max, tOFF = 12ns max). When powered from a +3V supply, the MAX4715/ MAX4716 offer 0.4 max on-resistance (RON) with 0.1 max RON flatness. Their digital logic inputs are +1.8V CMOS compatible when using a single +3V supply. The MAX4715 is pin compatible with the MAX4594, and the MAX4716 is pin compatible with the MAX4595. The MAX4715/MAX4716 are available in SC70-5 packages. o Low RON 0.4 max (+3V Supply) 1.2 max (+1.8V Supply) o 0.1 max RON Flatness (+3V Supply) o +1.6V to +3.6V Single-Supply Operation o Available in 5-Pin SC70 Packages o Fast Switching: tON = 18ns max, tOFF = 12ns max o +1.8V CMOS Logic Compatible (+3V Supply) o Pin Compatible with MAX4594 (MAX4715) Pin Compatible with MAX4595 (MAX4716) Features MAX4715/MAX4716 Applications Power Routing Battery-Operated Equipment Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Communications Circuits PCMCIA Cards Cellular Phones Modems Hard Drives MAX4715EXK-T MAX4716EXK-T -40C to +85C -40C to +85C PART Ordering Information TEMP.

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.

The MAX4715 is normally open (NO), and the MAX4716 is normally closed (NC). When powered from a +3V supply, their 0.4 R ON allows high continuous currents to be switched in a variety of applications. with a +3.3V supply, IN may be driven low to GND and high to +3.6V. Driving IN Rail-to-Rail(R) minimizes power consumption. Analog Signal Levels Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in on-resistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO, NC, and COM pins can be used as either inputs or outputs. Applications Information Logic Inputs The MAX4715/MAX4716 logic inputs can be driven up to +3.6V regardless of the supply voltage.
