Analog switches from the company are said to be ideal for high-speed switching of audio, video and data signals in portable devices such as mobile phones, MP3, CD/DVD and video players, digital cameras, and personal digital assistants. The high-speed, low-voltage, dual, single-pole/single-throw (SPST) analog switches are said to offer performance improvements over existing products. Switching time has been improved by over 40 percent while maintaining low on-resistance (Ron) flatness and channel matching. With a bandwidth of 130 MHz, the devices are said to be ideal for video and high-speed data signals. The supply voltage ranges from 1.6 V to 3.6 V and all digital logic inputs are 1.8 V CMOS compatible. The company says the combination of low power consumption, Ron and fast switching speed allows for switching of currents up to 250 mA. Switches are available as two normally open (AS1741), two normally closed (AS1742) and a combination of one open and one closed switch (AS1743) and are available in an 8-pin MSOP package and are drop-in replacements for MAX4741, MAX4742 and MAX4732.
