FSTD16211 24-Bit Bus Switch with Level Shifting June 2000 Revised August 2001 FSTD16211 24-Bit Bus Switch with Level Shifting General Description Features The Fairchild Switch FSTD16211 provides 24-bits of high-4Ω switch connection between two ports speed CMOS TTL-compatible bus switching. The low onVoltage level shifting 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 is organized as a 12-bit or 24-bit bus switch.Also packaged in plastic Fine-Pitch Ball Grid Array When OE is LOW, the switch is ON and Port 1A is con- 1 (FBGA) (Preliminary) nected to Port 1B. When OE is LOW, Port 2A is connected 2 to Port 2B. When OE is HIGH, a high impedance state 1/2 exists between the A and B Ports.
