¡El DG1411E, DG1412E, DG1413E are ± 15 V precision monolithic quad single-pole single-throw (SPST) CMOS analog switches. Built on a new CMOS process, the Vishay Siliconix DG1411E, DG1412E, and DG1413E offer low on-resistance of 1.5 . ¡El low and flat resistance over the full signal range ensures excellent linearity and low signal distortion. ¡El new CMOS platform provides low power dissipation, minimized parasitic capacitance, and low charge injection. ¡El devices operate from either a single 4.5 V to 24 V power supply, or from dual ± 4.5 V to ± 15 V power supplies. The analog switches do not require a VL logic supply, while all digital inputs have 0.8 V and 2 V logic thresholds to ensure low voltage TTL / CMOS compatibility. ¡El DG1411E, DG1412E, and DG1413E are bi-directional and support analog signals up to the supply voltage when on, and block them when off. ¡El devices each feature four independently selectable SPST switches. ¡El DG1411E is normally closed, while the DG1412E is normally open. The DG1413E has two normally open and two normally closed switches with guaranteed break-before-make operation. Combined with fast 70 ns switching time, low and flat switch resistance. ¡El devices are ideal for signal switching and relay replacement in data acquisition, industrial control and automation, communication, and A/V systems, in addition to medical instrumentation and automated test equipment. ¡El switches are available in RoHS-compliant, halogen-free TSSOP16 and QFN16 4 mm by 4 mm packages.
