#87486 - Two academic questions Responding to: ???'s previous message |
While not solving the original problem, I am curious whether
- a 2051 and an invertor (as Andy said) would be an appropriate solution for changing the edge of interrupt (and not "bending" the chip) - pin-compatible more modern replacement for 2051 with some extra features can be found (I am afraid not, the modern derivatives tend to be SMD with 40++ leads; and the Philips' '51 LPC family (here perhaps as true Low Pin Count :-) has no such member - I wonder, why?)
