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.
