TTL Compatible CMOS Analog Switches
General DescriptionMaxim’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
50Ωand 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 Configurationssection. The switch
control logic inputs are fully TTL and CMOS compati-
ble. 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-sup-
ply operation is implemented by connecting V- to GND.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICSStresses 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.

Applications Information
All DG300 family switches will operate with ±5V to ±15V
power supplies. They can also be used with single-ended
power supplies ranging from +10V to +30V where the V-
terminal is connected to ground. In either case, analog
signals ranging from V+ to V- can be switched.
The on-resistance variation with analog signal and supply
voltage is shown in the Typical Operating Characteristics.
The temperature coefficient of RONis typically 0.5%/°C.
Typical on-resistance matching from channel to chan-
nel is 10%. In addition, Table 1 outlines some typical
parameters for single-supply operation.
The charge injection test circuit is shown in Figure 1.
Table 2 lists the typical injected charge for DG300 series
switches with various input voltages.
