SANYO LC78212, LC78211 Datasheet

Applications

Function switching under serial data control in amplifiers,
receivers, and other electronic equipment

Features

• Two sets of eight (or in the LC78213, seven) built-in
circuits with three switching configurations available
based on differing internal connections

• Control according to serial data sent from a micro­processor, and easy connection to 5 V microprocessors

• Two identical products can be connected to a shared bus
due to the provision of a select pin (S).

• A reset pin that turns off all analog switches

• A ±20 V withstand voltage rating allows these products
to provide a wide dynamic range.
