Hello,
I am designing a circuit that requires 14 tri-state buffers. They could be controlled (enabled) in pairs or independently. All parts (having >4 gates) that I looked for are controlled (enabled) in 6 or 8 gates at the same time (with one ENABLE line) which does not suit my needs. I need them independently controlled (or in pairs max).
Currently I am using 74HC125D but it has only 4 gates, meaning I need 4 chips on board which is a bit too much - I am trying to scale down the size of device.
If there exists a tri-state buffer who's gates can be enabled/disabled via I2C - that's also a good option! Buffer could be inverting or non-inverting, I can handle that in firmware.
Thanks,
Muris
