Hello,
I'm trying to find out, what's the best way to get a logic device that outputs 5V to trigger something that requires 2.8V. Here's my thing:
I'm using an OR gate (74HC32) to trigger an analog switch that requires 2.8V to switch. My switching speeds will be very low (50Hz max). My switch draws little current (maybe 5mA), which the OR gate can source.
I'm thinking I need some kind of transistor set-up here, but I'm not sure what to I need to go with... mosfet? bjt? emitter-follower? pnp? pull-up, pull-down...
if anyone could point me in the right direction I would very much appreciate it.
much thanks!
