The Fairchild Video Switch FSAV330 is a quad single pole/double throw high-speed CMOS TTL-compatible video switch. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When OE# is LOW, the select pin connects the A Port to the selected B Port output. When OE# is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
