Low Voltage UHS 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 all ows input s to be conn ect ed
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 enab le (OE) signal. When OE is HIGH, th e switch is on an d Por t A is co nnected to Port B. When OE is LOW, the switch is open and
a high-impedance state exists bet ween the two ports.

Note 1: The “Absolute Maximum Ratings” are those values bey ond which
the safety of the d evice cannot be guaranteed. The device sh ould not be
operated at these limit s. The parametric values defin ed in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recomme nded O peratin g Cond itions ” table will defin e the condition s
for actual device operation.
Note 2: The input and output ne gative vo ltage ra tings may be excee ded 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 volta ge drop between A an d B pins at the indicated c urrent through the switch. On Resistance is determined by the lower of the
voltages on the two (A or B) pins.

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 ca pacitance, when driv en by an ideal voltage s ource (zero output imp edance).
