Revised August 2003 NC7WB66 TinyLogic Low Voltage UHS Dual SPST Normally Open Bus Switch General Description Features The NC7WB66 is an ultra high-speed (UHS) dual singlepole/single-throw (SPST) 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 highimpedance state exists between the two ports. The enable inputs tolerate voltages up to 5.5V independent of the VCC operating range. ■ Useful in both analog and digital applications ■ Space saving US8 surface mount package ■ MicroPak leadless package ■ Typical 7Ω On Resistance @ 5V VCC ■ Broad VCC operating range: 1.65V to 5.5V ■ Rail-to-rail signal handling ■ Power down high impedance control inputs ■ Control inputs are overvoltage tolerant ■ Control inputs are CMOS compatible Ordering Code: Product Order Number Package Code Package Description Supplied As Number Top Mark NC7WB66K8X MAB08A WB66 NC7WB66L8X MAC08A P4 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 3K Units on Tape and Reel 8-Lead MicroPak, 1.6 mm Wide 5K Units on Tape and Reel TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.

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.
