The DIO1568 is a quad single-pole, double-throw (SPDT) analog switch targeted at dual SIM card multiplexing. The DIO1568 operates from a single 1.65 V to 5.5 V supply and features an ultra-low on-resistance of 0.85 Ω at SIM path to ensure minimal voltage drop in other paths. This device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The DIO1568 features a very low quiescent current even when the control voltage is lower than the VCC supply. This allows mobile handset applications direct interface with the baseband processor general-purpose I/Os. The DIO1568 provides two Green packages: QFN1.8*2.6-16 and QFN3*3-16.

Maxim's MAX312/MAX313/MAX314 analog switches feature low on-resistance (10Ω max) and 1.5Ω on-resistance matching between channels. These switches conduct equally well in either direction. They offer low leakage over temperature (2.5nA at +85°C). Low power consumption and ESD tolerance greater than 2000V per Method 3015.7 are guaranteed. The MAX312/MAX313/MAX314 are quad, single-pole/single-throw (SPST) analog switches. The MAX312 is normally closed (NC), and the MAX313 is normally open (NO). The MAX314 has two NC switches and two NO switches. All three devices operate from a single supply of +4.5V to +30V or from dual supplies of ±4.5V to ±20V.
