FSA266 * NC7WB66 Low Voltage Dual SPST Normally Open Analog Switch or 2-Bit Bus Switch
May 2000 Revised December 2005
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

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 tables 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 inputs must be held HIGH or LOW. They may not float.
