| NC7SBU3157 * FSAU3157 TinyLogic Low Voltage UHS SPDT Analog Switch with -2V Undershoot Protection April 2002 Revised January 2003 NC7SBU3157 * FSAU3157 TinyLogic Low Voltage UHS SPDT Analog Switch with -2V Undershoot Protection General Description The NC7SBU3157 or FSAU3157 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. Fairchild's integrated Undershoot Hardened Circuit (UHC) senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning the switch on. Features s Useful in both analog and digital applications s Space saving SC70 6-lead surface mount package s Low On Resistance: < 10 on typ @ 3.3V VCC s Broad VCC operating range: 1.65V to 5.5V s Rail-to-Rail signal handling s Power down high impedance control input s Overvoltage tolerance of control input to 7.0V s Break before make enable circuitry s 250 MHz - 3dB bandwidth Ordering Code: Order Number NC7SBU3157P6X FSAU3157P6X Package Number MAA06A MAA06A Product Code Top Mark U7A U7A Package Description 6-Lead SC70, EIAJ SC88, 1.25mm Wide 6-Lead SC70, EIAJ SC88, 1.25mm Wide Supplied As 3k Units on Tape and Reel 3k Units on Tape and Reel TinyLogic is a registered trademark and UHC is a trademark of Fairchild Semiconductor Corporation.

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. 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.
