FAIRCHILD NC7SZ66M5X

Revised December 2005
NC7SZ66
Low Voltage Single SPST Normally Open Bus Switch
General Description
The NC7SZ66 is a ultra high-speed (UHS) CMOS compatible
single-pole/single-throw (SPST) 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 1bit 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.

Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety
of the device cannot be guaranteed. 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.

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) pins.
Note 5: All typical values are at the specified VCC, and TA
25qC.
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.

Note 9: This parameter is guaranteed by design but is not tested. The switch contributes no propagation delay other than the RC delay of the typical On Resistance of the switch
and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
