DG303

19-0309; Rev 3; 11/07 TTL Compatible CMOS Analog Switches DG300(A)/DG301(A)/DG302(A)/DG303(A) General Description Maxim’s DG300–DG303 and DG300A–DG303A CMOS dual and quad analog switches combine low power operation with fast switching times and superior DC and AC switch characteristics. On-resistance is less than 50Ω and is essentially constant over the analog signal range. Device specifications are ideal for batterypowered circuitry. These switches are available in a variety of formats as outlined in the Pin Configurations section. The switch control logic inputs are fully TTL and CMOS compatible. Also featured are “break-before-make” switching and low charge injection. Maxim’s DG300-DG303 and DG300A-DG303A families are electrically compatible and pin compatible with the original manufacturer’s devices. All devices operate with power supplies ranging from ±5V to ±18V. Single-supply operation is implemented by connecting V- to GND.
