NC7SZ66
TinyLogic Low Voltage UHS Single SPST
Normally Open Bus Switch
General Description
The NC7SZ66 is a ultra high-speed (UHS) CMOS compati-
ble 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 gen-
erating additional ground bounce noise. The device is
organized as a 1-bit switch with a switch enable (OE) sig-
nal. When OE is HIGH, the switch is on and Port A is con-
nected to Port B. When OE is LOW, the switch is open and
a high-impedance state exists between the two ports.
