BCT4717
4.0, 300MHz Bandwidth, Dual SPDT Analog Switch
GENERAL DESCRIPTION
The BCT4717 is a dual, bidirectional,
single-pole/double- throw (SPDT) CMOS analog switches
designed to operate from a single +1.8V to +5.5V supply. It
features high-bandwidth (300MHz) and low ON-resistance
(4.0Ω typ), Targeted applications for audio switching.
BCT4717 features guaranteed on-resistance matching
(0.3Ω max) between switches and guaranteed on-resistance
flatness over the signal range (2.3Ω TYP). This ensures
excellent linearity and low distortion when switching audio
signals.
The BCT4717 is a committed dual single-pole/double
-throw (SPDT) that consist of two normally open (NO) and
two normally close (NC) switches. This configuration can
be used as a dual 2-to-1 multiplexer.
BCT4717 is available in WQFN-10 package.

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.
(1) Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum
current ratings.
