FST16233
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 (S₁, S₀) and two test (TEST₀, TEST₁) inputs
provide switch enable and multiplexer select control.
The FST16233 is designed to prevent through-current
when switching buses.
Features
s 4Ω switch connection between two ports.
s Minimal propagation delay through the switch.
s Low l_CC.
s Zero bounce in flow-through mode.
s Control inputs compatible with TTL level.
