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.

FSA266 • NC7WB66
Low Voltage Dual SPST
Normally Open Analog Switch or 2-Bit Bus Switch
General Description
The FSA266 or NC7WB66 is an ultra high-speed (UHS) dual
single-pole/single-throw (SPST) analog switch or 2-bit bus
switch. The device is fabricated with advanced sub-micron
CMOS technology to achieve high speed enable and disable
times and low On Resistance over a broad VCC range. The
device is specified to operate over the 1.65 to 5.5V VCC operating range. The device is organized as a dual switch with independent CMOS compatible switch enable (OE) controls. 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. The enable inputs tolerate
voltages up to 5.5V independent of the VCC operating range.
Features
O Useful in both analog and digital applications
O Space saving US8 surface mount package
O MicroPak¥ Pb-Free leadless package
O Typical 7: On Resistance @ 5V VCC
O Broad VCC operating range: 1.65V to 5.5V
O Rail-to-Rail signal handling
O Power down high impedance control inputs
O Control inputs are overvoltage tolerant
O Control inputs are CMOS compatible
O !300 MHz 3dB bandwidth
