| NC7SB121 TinyLogic Low Voltage UHS Single SPST Wide Bandwidth Normally Open Analog Switch October 2001 Revised October 2001 NC7SB121 TinyLogic Low Voltage UHS Single SPST Wide Bandwidth Normally Open Analog Switch General Description The NC7SB121 is a ultra high-speed (UHS) CMOS compatible single-pole/single-throw (SPST) analog switch or 1-bit bus switch. The LOW on resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 1-bit switch with a switch enable (OE) signal. 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. Features s Space saving SOT23 or SC70 5-lead package s Ultra small MicroPak leadless package s Broad VCC Operating Range 2V-5.5V s Rail-to-rail signal handling s 7.2 switch connection between two ports s Minimal propagation delay through the switch s Low ICC s Zero bounce in flow-through mode s Control input compatible with CMOS input levels s >326 MHz -3dB bandwidth s Improved package replacement for the P15A121 Ordering Code: Order Number NC7SB121M5X NC7SB121P5X NC7SB121L6X Package Number MA05B MAA05A MAC06 (Preliminary) Product Code Top Mark 7B21 B21 21 Package Description 5-Lead SOT23, JEDEC MO-178, 1.6mm 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 6-Lead MicroPak, 1.0mm Wide Supplied As 3k Units on Tape and Reel 3k Units on Tape and Reel 5k Units on Tape and Reel TinyLogic and MicroPak are trademarks of Fairchild Semiconductor Corporation.

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.

On Resistance is determined by the lower of the voltages on the two (A or B) pins. Note 5: All typical values are at the specified VCC, and TA = 25C. Note 6: Parameter is characterized but not tested in production. Note 7: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
