Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FST16233
16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch
General Description
Features
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.
■ 4Ω switch connection between two ports.
■ Minimal propagation delay through the switch.
■ Low lCC
.
■ Zero bounce in flow-through mode.
■ Control inputs compatible with TTL level.
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.

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3: Unused control inputs must be held HIGH or LOW. They may not
float.
