General Description
The ET7428 is an advanced CMOS analog switch fabricated in Sub−micron silicon gate CMOS technology.
The part also features guaranteed Break Before Make (BBM) switching, assuring the switches never short the driver. The switches can handle negative signal down to -3.6V. When the voltage of the COM terminal exceeds OVP threshold, the channels from the COM terminal to the NC and NO terminals will be turned off.
ET7428 is offered in a small QFN10L package, which is ideal for small form factor portable equipment.
