... MAX4748 is a hex single-pole/double- throw (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™ ...

... 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 disabled, and the analog inputs enter a high-impedance state. Drive EN low to turn the switches on and enable CB ...
