#91276 - Why not use 2N7000 Responding to: ???'s previous message |
Driving relays is a a breeze using FETs and interfaces directly to 8031's. You only need a diode across relay.
Example: 2N7000 turns ON with <4.5V and has an ON resistance <2 ohms. see: http://www.ee.washington.edu/stores/Da...2n7000.pdf Peter |
