0.5Ω, 3.3V Quad-SPDT Analog Switch
GENERAL DESCRIPTION
FEATURES
The BCT4699 is configured as a quad-
SPDT switch with two common control
inputs. Each digital input controls two pairs
of SPDT switches. The switches are fully
bi-directional, allowing both multiplexing
and de-multiplexing operation. Break-
before-make operation is guaranteed.
The device operates from a +1.8V to
+5.0V supply and over the extended -40°C
to +85°C temperature range. It is offered
in 16-pin 3mm x 3mm TQFN package.
