FST16210 20-Bit Bus Switch November 1998 Revised December 1999 FST16210 20-Bit Bus Switch General Description Features The Fairchild Switch FST16210 provides 20-Bits of high-4Ω switch connection between two ports. speed CMOS TTL-compatible bus switching. The low onMinimal propagation delay through the switch. resistance of the switch allows inputs to be connected to Low l . CC outputs without adding propagation delay or generating Zero bounce in flow-through mode. additional ground bounce noise. Control inputs compatible with TTL level. The device is organized as a 10-bit or 20-Bit bus switch. When OE is LOW, the switch is ON and Port 1A is con- 1 nected to Port 1B. When OE is LOW, Port 2A is connected 2 to Port 2B.
