MAX4624/MAX4625 19-1592 Rev 2 5/01 1 , Low-Voltage, Single-Supply SPDT Analog Switches General Description Features The MAX4624/MAX4625 are low-on-resistance, low- Low R ON voltage single-pole/double-throw (SPDT) analog switch- 1 max (+5V Supply) es that operate from a single +1.8V to +5.5V supply. 2 max (+3V Supply) The MAX4624 has break-before-make switching the 0.12 max R Flatness (+5V Supply) ON MAX4625 has make-before-break switching. These devices also have fast switching speeds (t = 50ns ON Overcurrent Protection max, t = 50ns max). OFF +1.8V to +5.5V Single-Supply Operation When powered from a +5V supply, the MAX4624/ MAX4625 offer 1 max on-resistance (R ), with 0.12 ON Available in SOT23 Packages max R matching and flatness. The digital logic ON Fast Switching: t = 50ns max, t = 50ns max ON OFF inputs are TTL compatible when using a single +5V supply. These switches also feature overcurrent protec- TTL-Logic Compatible (+5V Supply) tion to prevent damage from short circuits and exces- Pin Compatible with MAX4544 sive loads. The MAX4624/MAX4625 are pin compatible with the Guaranteed Break-Before-Make (MAX4624) MAX4544 and are available in space-saving standard Guaranteed Make-Before-Break (MAX4625) 6-pin SOT23 packages, as well as the 1.0mm high Thin SOT package.

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.
