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.

NC7SZ66
Low Voltage Single SPST Normally Open Bus Switch
Features
Description
The NC7SZ66 is a ultra high-speed (UHS) CMOS
compatible single-pole/single-throw (SPST) bus switch.
The LOW on resistance of the switch allows inputs to be
connected to outputs with minimal propagation delay
and without generating additional ground bounce noise.
The device is organized as a 1-bit switch with a switch
enable (OE) signal. When OE is HIGH, the switch is on
and port A is connected to port B. When OE is LOW, the
switch is open and a high-impedance state exists
between the two ports..
Broad VCC Operating Range: 1.65 V to 5.5 V
Rail-to-Rail Signal Handling
Power Down High-Impedance Inputs/Outputs
5 Ω Switch Connection between Two Ports
Minimal Propagation Delay through the Switch
Low ICC
Zero Bounce in Flow-Through Mode

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
