NC7SB3157
TinyLogic Low Voltage UHS Analog Switch 2-Channel
Multiplexer/Demultiplexer
General Description
Features
The NC7SB3157 is a high performance, Analog Switch 2channel CMOS multiplexer/demultiplexer from Fairchild’s
Ultra High Speed Series of TinyLogic. The device is fabricated with advanced sub-micron CMOS technology to
achieve high speed enable and disable times and low on
resistance. The break before make select circuitry prevents
disruption of signals on the B Port due to both switches
temporarily being enabled during select pin switching. The
device is specified to operate over the 1.65 to 5.5V VCC
operating range. The control input tolerates voltages up to
5.5V independent of the VCC operating range.
■ Useful in both analog and digital applications
■ Space saving SC70 6-lead surface mount package
■ Low on resistance; < 10Ω on typ @ 3.3V VCC
■ Broad VCC operating range; 1.65V to 5.5V
■ Power down high impedance control input
■ Overvoltage tolerance of control input to 7.0V
■ Break before make enable circuitry

Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifications should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications.
180 mW
Note 2: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3: Control input must be held HIGH or LOW, it must 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 Ports).
Note 5: Parameter is characterized but not tested in production.
Note 6: ∆RON = RON max − RON min measured at identical VCC, temperature and voltage levels.
Note 7: Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified range of conditions.
