DG300A:TTL Compatible CMOS Analog Switches

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 battery-powered circuitry. These switches are available in a variety of formats as outlined in the Pin Configurations section in the full data sheet. 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.
