2SC1815 Buffer Toggle

[C.A.R.G]

Hello All,

I'm building a 6-Loop relay switcher with an input and output buffer that can be toggled on/off. I intend on using the attached 2SC1815 buffer circuit but haven't the onboard space for an extra bypass circuit per buffer. Would it be good practice to toggle the buffer by simply removing the 9V power supply?

Hi & Welcome..

A buffer with removed power supply is a dead silent buffer..
(signal doesn't come out of Emitter..)

P.S.
For 2 buffers, utilize Beavis last op-amp configuration..
(the one with TL072)
