Description
Control inputs compatible with TTL level
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
All input/output pins are on the same side

■
Guaranteed break-before-make timing
High ESD rating: > 2kV HBM
switch allows inputs to be connected to outputs
without adding propagation delay or generating
additional ground bounce noise.
■ –40°C to 85°C operating temperature range
■
Suitable for both RGB and Composite-Video
Switching
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.
■ Available in a small TSSOP16 package
Applications
■ Advanced TVs
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.

Summary Description
1.1
Functional Description
The STMAV340 is a high bandwidth, analog video switch. It is low ON-resistance and low I/O
capacitance result in a very small propagation delay.
When OE_N is set to LOW, the select (S) pin connects port A to the selected port B or port C
output. When OE_N is set to HIGH, the switch is OPEN and a high-impedance state exists
between the A port and B/C ports.
Low differential gain and phase make this switch ideal for component and RGB video
applications. This device has high bandwith and low crosstalk, making it ideal for high
frequency applications as well.

Maximum Ratings
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of this
specification is not implied. Exposure to Absolute Maximum Rating conditions for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and
other relevant quality documents.
