20-Bit Bus Switch
General Description
The Fairchild Switch FST16210 provides 20-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 device is organized as a 10-bit or 20-Bit bus switch.
