¡El DG2501, DG2502, and DG2503 are monolithic quad single-pole single-throw (SPST) analog switches that operate from a single 1.8 V to 5.5 V power supply. These switches are fully specified at 3 V and 5 V. ¡El parts feature low parasitic capacitance, low charge injection, and low leakage performance over the full operating temperature range of -40 °C to +85 °C. Their ESD/HBM tolerance is over 8 kV. ¡El DG2501, DG2502, and DG2503 each feature four independently selectable SPST switches with closely matched channel resistance. ¡El DG2501 is normally closed, while the DG2502 is normally open. ¡El DG2503 has two normally open and two normally closed switches. All parts are guaranteed break-before-make operation for use in multiplexer applications. ¡El parts have a guaranteed control logic high of 1.4 V when V+ is 3 V and 1.8 V when V+ is 5 V. Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the supplies. ¡El DG2501, DG2502, and DG2503 are ideal for portable healthcare, instrument, and communication devices. ¡El DG2501, DG2502, and DG2503 are available in wafer level CSP package with top side lamination. ¡El package has a 4 x 4 bump array, 0.35 mm pitch, and 1.44 mm x 1.44 mm length and width.
