Title: [Req.] Bidirectional Analog Switch Post by: puta on September 12, 2008, 11:32:30 23:32 Could anyone tell me Bidirectional analog (or TTL) switch with tristatea semiconductor IC . I need to on/off some electronic device's push button through a microcontroller, and signal could be either direction.
(I/O) < > < > (I/O) o-----. .-----o / | | o Control (Through microcontroller) I have been serching this without success. Please help. Title: Re: [Req.] Bidirectional Analog Switch Post by: mylogin on September 13, 2008, 01:53:39 01:53 try 74cbt3383, or 74cbt3384, or 74cbt series FET signal switch chip.
they are cheap and has very low on-resistance(5 to 7 ohms), excellent for analog/video/digital I/O bi-directional switch applications. we have used it a lot in bi-directional video switch.
