Description

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/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 (active-low 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™).
