19-0673; Rev 1; 1/07 KIT ATION EVALU E L B AVAILA Hex SPDT Data Switch The MAX4947/MAX4948 analog switches operate from a single +1.8V to +5.5V supply. These switches feature a low 30pF (typ) capacitance for high-speed data switching applications. The MAX4947 is a triple double-pole/double-throw (DPDT) switch, and the MAX4748 is a hex single-pole/doublethrow (SPDT) switch with one control logic input. The MAX4947 has three logic inputs to control the switches in pairs. The MAX4948 has one logic input and an enable input (EN) to disable the switches. The MAX4947/MAX4948 are available in small 24-pin (4mm x 4mm) TQFN and 25-bump (2.5mm x 2.5mm) chip-scale packages (UCSP™).

These devices are fully specified for +3V applications. The MAX4947/MAX4948 have a guaranteed 4Ω (typ) onresistance and a low 30pF (typ) capacitance that makes the switch ideal for data switching applications. The MAX4947 has three logic inputs to control two switches in pairs and the MAX4948 has one logic control input and an enable input (EN) to disable the switches. Applications Information Digital Control Inputs The MAX4947/MAX4948 provide a digital control logic input, CB_. CB_ controls the position of the switches as shown in the Pin Configurations/Truth Tables. Driving CB_ rail-to-rail minimizes power consumption. The MAX4948 features an EN input to turn all switches on or off. When EN is driven high, CB is disabled, and the analog inputs enter a high-impedance state. Drive EN low to turn the switches on and enable CB. Analog Signal Levels The on-resistance of the MAX4947/MAX4948 is very low and stable as the analog input signals are swept from ground to V CC (see the Typical Operating Characteristics). These switches are bidirectional, allowing NO_, NC_, and COM_ to be configured as either inputs or outputs. Power-Supply Biasing Power-supply bypassing improves noise margin and prevents switching noise to propagate from VCC supply to other components. A 0.1µF capacitor connected from V+ to GND is adequate for most applications. Power-Supply Sequencing CMOS devices require proper power-supply sequencing. Always apply VCC before the analog signals, especially if the input signal is not current limited.
