19-1982; Rev 1; 5/04 0.8, Low-Voltage, Single-Supply SPDT Analog Switch in SC70 The MAX4714 is a low on-resistance, low-voltage single-pole/double-throw (SPDT) analog switch that operates from a single +1.6V to +3.6V supply. The MAX4714 has break-before-make switching. This device also has fast switching speeds (tON = 18ns, max, tOFF = 12ns, max). When powered from a +3V supply, the MAX4714 features 0.8 (max) on-resistance (RON), with 0.18 (max) RON matching and flatness. The digital logic input is 1.8V CMOS compatible when using a single +3V supply. The MAX4714 is pin compatible with the MAX4599 and is available in a 6-pin SC70 or DFN package.

MAX4714 0.8, Low-Voltage, Single-Supply SPDT Analog Switch in SC70 Detailed Description The MAX4714 is a low-on-resistance (RON), low-voltage, single-pole/double-throw (SPDT) analog switch that operates from a +1.6V to +3.6V supply. The MAX4714 has break-before-make switching. This device also has fast switching speeds (tON = 18ns, max, tOFF = 12ns, max). When powered from a +3V supply, the 0.8 (max) RON allows high continuous currents to be switched in a variety of applications. +3.3V supply, IN may be driven low to GND and high to +3.6V. Driving IN rail-to-rail 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. Chip Information Applications Information Logic Inputs The MAX4714 logic input can be driven up to +3.6V regardless of the supply voltage.
