24-Bit Bus Exchange Switch
General Description
The Fairchild Switch FST16212 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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
