NC7WB66
TinyLogic Low Voltage UHS Dual SPST
Normally Open Bus Switch
General Description
Features
■ Useful in both analog and digital applications
■ Space saving US8 surface mount package
■ MicroPak leadless package
The NC7WB66 is an ultra high-speed (UHS) dual single-
pole/single-throw (SPST) bus switch. The device is fabri-
cated 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 speci-
■ Typical 7Ω On Resistance @ 5V VCC
■ Broad VCC operating range: 1.65V to 5.5V
fied 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
■ Rail-to-rail signal handling
■ Power down high impedance control inputs
■ Control inputs are overvoltage tolerant
■ Control inputs are CMOS compatible
operating range.

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.

Note 4: Measured by the voltage drop between A and B pins at the indicated current through the switch. On resistance is determined by the lower of the
voltages on the two (A or B) pins.
Note 5: Guaranteed by design.
Note 6: Flatness is defined as the difference between the minimum and maximum value of ON resistance over the specified range of conditions.
Note 7: ∆RON = RON max − RON min measured at identical VCC, temperature and voltage levels.
