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.
Applications
Portable Instruments
Low-Power Sample/Holds

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(V+ = +15V, V- = -15V, GND = 0V, TA= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

rent ratings.
Note 2: The algebraic convention whereby the most negative value is a minimum, and the most positive value is a maximum is used
in this data sheet.
