TC7WBD125FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WBD125FK
Dual Bus Switch with Level Shift
The TC7WBD125FK 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 internal diode which adds to power supply line is enable to
realize the shift of signal level from 5 V to 3.3 V. (Note 1)
All inputs are equipped with protector circuits to protect the
device from static discharge.
Weight: 0.01 g (typ.)

•
TTL level input (control input)
•
Package: US8
Note 1: In case that over-shoot noise is detected, this device should be used with clamp diode to prevent the next
stage device from over-stress.
