FST32211

The Fairchild Switch FST32211 provides up to 48-bits of high-speed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

The FST32211 can be organized as four 12-bit, two 24-bit, or one 48-bit bus switch. When routed as a 40-bit bus switch,the device can be organized as four 10-bit, two 20-bit or one 40-bit bus switch. When OE₁ is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE₂ is LOW,the switch is ON and Port 2A is connected to Port 2B. When OE₃ is LOW, the FST32211 is ON and Port 3A is connected to Port 3B. When OE₄ is LOW, the switch is ON and Port 4A is connected to Port 4B. When OE₁, OE₂, OE₃, or OE₄ are HIGH, a high impedance state exists between the A and B Ports.
