Description
TC7WBD125AFK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WBD125AFK
Dual Bus Switch with Level Shift
The TC7WBD125AFK is a low on-resistance, high-speed CMOS 2-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 low level, the switch is on; when at high level, the switch is off.
The device is enable to realize the shift of signal level from 5 V to 3.3 V.
All inputs are equipped with protector circuits to protect the device from static discharge.
Features
