19-3037; Rev 3; 7/07 High-Bandwidth, Quad DPDT Switches The MAX4760/MAX4761 (DPDT) analog switches operate from a single +1.8V to +5.5V supply. These switches feature a low 25pF capacitance for high-speed data switching applications. The MAX4760 is a quad double-pole/double-throw (DPDT) switch and the MAX4761 is an octal singlepole/double-throw (SPDT) switch. They have eight 3.5Ω on-resistance, low-capacitance switches to route audio and data signals. The MAX4760 has 4 logic inputs to control the switches in pairs. The MAX4761 has one logic control input and an enable input (EN) to disable the switches. The MAX4760/MAX4761 are available in a small 36-pin (6mm x 6mm) thin QFN and 36-bump (3mm x 3mm) chip-scale package (UCSP™).

These devices are fully specified for +3V applications. The MAX4760/MAX4761 have a guaranteed 3.5Ω (max) on-resistance to switch data or audio signals. The low 25pF capacitance and 0.2ns change in skew makes them ideal for data switching applications. The MAX4760 has 4 logic inputs to control two switches in pairs and the MAX4761 has one logic control input and an enable input (EN) to disable the switches. Applications Information Digital Control Inputs The MAX4760/MAX4761 logic inputs accept up to +5.5V regardless of the supply voltage. For example, with a +3.3V supply, IN_ can be driven low to GND and high to +5.5V, which allows mixed logic levels in a system. Driving the control logic inputs rail-to-rail also minimizes power consumption. For a +3V supply voltage, the logic thresholds are 0.5V (low) and 1.4V (high). For the MAX4761, drive EN low to enable. When EN is high, COM_ is high impedance. Analog Signal Levels Analog signal inputs over the full voltage range (0V to V+) are passed through the switch with minimal change in onresistance (see the Typical Operating Characteristics). The switches are bidirectional so NO_, NC_, and COM_ can be either inputs or outputs. Power-Supply Bypassing Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ supply to other components. A 0.1µF capacitor connected from V+ to GND is adequate for most applications. POSITIVE SUPPLY V+ D1 MAX4760 MAX4761 NO COM GND Figure 1. Overvoltage Protection Using an External Blocking Diode Power-Supply Sequencing CMOS devices require proper power-supply sequencing. Always apply V+ before the analog signals, especially if the input signal is not current limited. If sequencing is not possible, and the input signal is not current limited to less than 20mA, add a small-signal diode (Figure 1). Adding the diode reduces the analog range to a diode drop (0.7V) below V+ and increases the on-resistance slightly. The maximum supply voltage must not exceed +6V at any time.
