TTL Compatible CMOS Analog Switches
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 battery-
powered 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 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.
