I am trying to use a single uC i/o Pin To toggle a PWM output between two mosfets ... Easily done with 5 NAND gates, but I would like to achieve it with a single 74xxxx IC and the logic is killing me ;-)
Here is the Logic I need:
Goal would be a single 74xxxx IC (doesn't have to be a NAND gate) ... Don't want to use a PLA ... a second Logic IC or a uC with more i/o Pins ... It may not be possible ... I just thought I would see if anyone could at least tell me if it is NOT possible before I waste a whole day on it.
Thanks in Advance!

Here is the Logic I need:
Code:
; A | B | Out1 | Out2 |
;---|---|------|------|
; 1 | 1 | 1 | 0 |
;---|---|------|------|
; 0 | 1 | 0 | 1 |
;---|---|------|------|
; x | 0 | 0 | 0 |
;---|---|------|------|
