MAX4996/MAX4996L 19-4036 Rev 0 2/08 Triple DPDT, Low-Capacitance Data Switches General Description Features The MAX4996/MAX4996L triple DPDT analog switches Multiplex SD2.0/SDIO Interfaces operate from a single +2.5V to +5.5V supply, and fea- Low Power Consumption (2A max) ture 2.0 (typ) on-resistance, low 6pF (typ) on-capaci- tance, and low power-supply current consumption. The +2.5V to +5.5V Supply Voltage Range MAX4996/MAX4996L combine the low capacitance and Rail-to-Rail Signal Handling low resistance necessary for high-frequency switching applications in portable electronics. Low-Capacitance Switches, 6pF (typ) The MAX4996/MAX4996L have three logic inputs to Low On-Resistance, 2 (typ) control the switches in pairs. The MAX4996 has an active-high enable input (EN) to disable the switches, Excellent On-Resistance Flatness Over the Range while the MAX4996L has an active-low enable input of 0V to V CC (EN) to disable the switches. The enable input decreas- Wide -3dB Bandwidth, 670MHz es the supply current and also places the COM out- puts in a high-impedance state. Small 24-Pin TQFN (3.5mm x 3.5mm) The MAX4996/MAX4996L feature a 5A (max) supply- current consumption when the logic inputs are not Pin Configuration/Truth Tables rail-to-rail. This feature is especially valuable in applica- tions where direct interface to low-voltage processors TOP VIEW is necessary. The MAX4996/MAX4996L are available in a space- saving 24-pin (3.5mm x 3.5mm) TQFN package and operate over the -40C to +85C temperature range.

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. ELECTRICAL CHARACTERISTICS (V = +2.5V to +5.5V, T = -40C to +85C, unless otherwise noted.
