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 V_CC range. The
device is specified to operate over the 1.65 to 5.5V V_CC operat-
ing range. The device is organized as a dual switch with inde-
pendent 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 V_CC operating range.
