NC7SB3157P6X - Fairchild Semiconductor

NC7SB3157, FSA3157
Low-Voltage SPDT Analog Switch or 2:1Multiplexer /
De-multiplexer Bus Switch
Features
Description
■ Useful in Both Analog and Digital Applications
The NC7SB3157 / FSA3157 is a high-performance, single-pole / double-throw (SPDT) analog switch or 2:1 multiplexer / de-multiplexer bus switch.
■ Space-Saving, SC70 6-Lead Surface Mount Package
■ Ultra-Small, MicroPak™ Leadless Package
■ Low On Resistance: <10Ω on Typical at 3.3V VCC
■ Broad VCC Operating Range: 1.65V to 5.5V
■ Rail-to-Rail Signal Handling
■ Power-Down, High-Impedance Control Input
■ Over-Voltage Tolerance of Control Input to 7.0V
■ Break-Before-Make Enable Circuitry
■ 250MHz, 3dB Bandwidth
The device is fabricated with advanced sub-micron
CMOS technology to achieve high-speed enable and
disable times and low on resistance. The break-beforemake 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.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Notes:
3. 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).
4. Parameter is characterized, but not tested in production.
5. ΔRON = RON max – RON minimum measured at identical VCC, temperature, and voltage levels.
6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified
range of conditions.
7. Guaranteed by design.
