Low Voltage UHS Dual SPST
Normally Open Bus Switch
General Description
The NC7WB66 is an ultra high-speed (UHS) dual single-
pole/single-throw (SPST) bus switch. The device is fabri-
cated with advanced sub-micron CMOS technology to
achieve high speed enable and disable times and low On
Resistance over a broad V
CC
range. The device is speci-
fied to operate over the 1.65 to 5.5V V
CC
operating range.
The device is organized as a dual switch with independent
CMOS compatible switch enable (OE) controls. 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. The enable
inputs tolerate voltages up to 5.5V independent of the V
CC
operating range.
