TinyLogic

 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

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

operating range.
