TC7WBL125FK

Dual Low-Voltage Bus Switch

The TC7WBL125FK is a low on-resistance, high-speed CMOS
2-bit bus switch with low voltage operation. 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.

P-MOS and N-MOS channel block also allows that the device is
suitable for analog signal transmission.

All inputs are equipped with protection circuits to protect the
device from static discharge.
