16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch
General Description
The Fairchild Switch FST16233 is a 16-bit to 32-bit high-
speed CMOS TTL-compatible multiplexer/demultiplexer
bus switch. The low on resistance of the switch allows
inputs to be connected to outputs without adding propaga-
tion delay or generating additional ground bounce noise.
The device can be used in applications where two buses
need to be addressed simultaneously. The FST16233 can
be used as two 8-bit to 16-bit multiplexers or as one 16-bit
to 32-bit multiplexer.
Two select (SEL
inputs provide switch enable and multiplexer select control.
The FST16233 is designed to prevent through-current
when switching buses.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
