24-Bit Bus Exchange Switch
The Fairchild Switch FST16213 provides 24-bits of high-
speed CMOS TTL-compatible bus switching or exchang-
ing. 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 operates as a 24-bit bus switch or a 12-bit bus
exchanger, which allows data exchange between the four
signal ports via the data-select terminals.
s 4Ω switch connection between two ports.
s Minimal propagation delay through the switch.
s Low lCC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
