TOSHIBA TC7WB66FK

TC7WB66FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WB66FK
Dual Bus Switch
The TC7WB66FK is a low on-resistance, high-speed
CMOS2-bit bus switch. This bus switch allows the connections or
disconnections to be made with minimal propagation delay while
maintaining Low power dissipation which is the feature of
CMOS.
When output enable (OE) is at High level, the switch is on;
when at Low level, the switch is off.
P-MOS and N-MOS channel block means the device is suitable
for analog signal transmission.
All inputs are equipped with protector circuits to protect the
device from static discharge.
