Description
The STMAV340 is a bidirectional quad (4
channel), high speed single pole/double throw
(SPDT), low power CMOS TTL-compatible analog
video switch designed for advanced video
applications which demand superior image
quality. The low ON Resistance (RON) of the
switch allows inputs to be connected to outputs
without adding propagation delay or generating
additional ground bounce noise.
STMAV340 is designed for very low cross-talk,
low bit-to-bit skew, high channel-to-channel noise
isolation, and low I/O capacitance. The switch
offers very little or practically no attenuation of the
high speed signals at the outputs, thus preserving
the signal integrity enough to pass stringent
requirements.
The STMAV340 is able to simplify the PCB routing
on inputs and outputs as well as reduce the
overall BOM costs by eliminating the need for
more costly input-output controllers.
