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.

FSTD16211
24-Bit Bus Switch with Level Shifting
General Description
Features
The Fairchild Switch FSTD16211 provides 24-bits of high-
speed CMOS TTL-compatible bus switching. The low On
Resistance of the switch allows inputs to be connected to
outputs without adding propagation delay or generating
additional ground bounce noise. A diode to VCC has been
■ 4 switch connection between two ports
■ Voltage level shifting
■ Minimal propagation delay through the switch
■ Low lCC
■ Zero bounce in flow-through mode
integrated into the circuit to allow for level shifting between
5V inputs and 3.3V outputs.
■ Control inputs compatible with TTL level
The device is organized as a 12-bit or 24-bit bus switch.
When OE1 is LOW, the switch is ON and Port 1A is con-
■ Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
nected to Port 1B. When OE2 is LOW, Port 2A is connected
to Port 2B. When OE1/2 is HIGH, a high impedance state
exists between the A and B Ports.

Note 3: 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.
