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.

FST3384
10-Bit Low Power Bus Switch
General Description
Features
■ 4Ω switch connection between two ports
■ Minimal propagation delay through the switch
■ Ultra low power with < 0.1 µA typical ICC
The Fairchild Switch FST3384 provides 10 bits of high-
speed CMOS TTL-compatible bus switches. 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 is organized
as two 5-bit switches with separate bus enable (OE) sig-
nals. When OE is LOW, the switch is ON and Port A is con-
nected to Port B. When OE is HIGH, the switch is OPEN
and a high-impedance state exists between the two ports.
■ Zero ground bounce in flow-through mode
■ Control inputs compatible with TTL level

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” table are not guaranteed at the absolute maximum ratings.
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.
