TS3V330,pdf(QUAD SPDT WIDE-BAN

The TS3V330 video switch is a 4-bit 1-of-2 multiplexer/demultiplexer, with a single switch-enable (EN) input. When EN is low, the switch is enabled and the D port is connected to the S port. When EN is high, the switch is disabled and the high-impedance state exists between the D and S ports. The select (IN) input controls the data path of the multiplexer/demultiplexer.

Low differential gain and phase make this switch ideal for composite and RGB video applications. This device has wide bandwidth and low crosstalk, making it suitable for high-frequency applications as well.

This device is fully specified for partial-power-down applications using I_off. The I_off feature ensures that damaging current will not backflow through the device when it is powered down. This switch maintains isolation during power off.

To ensure the high-impedance state during power up or power down, EN should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
