General Description
The Fairchild Universal Bus Switch FSTUD162450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit 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.

Features
■ Undershoot protected to −2V (A and B Ports)
■ Voltage level shifting
■ 25Ω switch connection between two ports
■ Minimal propagation delay through the switch
■ Low lCC
■ Zero bounce in flow-through mode
■ Control inputs compatible with TTL level
■ See Applications Notes AN-5008 and AN-5021 for UHC details
■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary)
