TC4W66FU Datasheet PDF - Toshiba

Dual bilateral switch CMOS digital integrated circuit silicon monolithic The TC4W66FU contains two independence circuits of bidirectional switches. When conrtol input CONT is set to "H" level,the impendance between input and output of the switch becomes low and when it is set to "L" level, the switch becomes high. This can be applied for switching of analog signals and digital signals.
