FSTD32211 40/48-Bit Bus Switch with Level Shifting September 2001 Revised July 2002 FSTD32211 40/48-Bit Bus Switch with Level Shifting General Description Features The Fairchild Switch FSTD32211 provides up to 48-bits of � 4Ω switch connection between two ports high-speed CMOS TTL-compatible bus switching. The low � Voltage level shifting on resistance of the switch allows inputs to be connected to � Minimal propagation delay through the switch outputs without adding propagation delay or generating � Low l CC additional ground bounce noise. A diode to V has been CC � Zero bounce in flow-through mode integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs. � Control inputs compatible with TTL level The device can be organized as four 12-bit, two 24-bit, or � Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) 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 OE is LOW, the switch is ON 1 and Port 1A is connected to Port 1B. When OE is LOW, 2 the switch is ON and Port 2A is connected to Port 2B. When OE is LOW, the switch is ON and Port 3A is con- 3 nected to Port 3B. When OE is LOW, the switch is ON and 4 Port 4A is connected to Port 4B. When OE , OE , OE , or 1 2 3 OE are HIGH, a high impedance state exists between the 4 A and B Ports.
