NC7SB3157 • FSA3157
TinyLogic Low Voltage UHS SPDT Analog Switch
or 2:1 Multiplexer/Demultiplexer Bus Switch
General Description
Features
The NC7SB3157 or FSA3157 is a high performance, single-pole/double-throw (SPDT) Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch 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
■ Ultra small MicroPak leadless package
■ Low On Resistance; < 10Ω on typ @ 3.3V VCC
■ Broad VCC operating range; 1.65V to 5.5V
■ Rail-to-Rail signal handling
■ Power down high impedance control input
■ Overvoltage tolerance of control input to 7.0V
■ Break before make enable circuitry
■ 250 MHz - 3dB bandwidth

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.
