#148149 - why use discretes whern a cheap chip exist. Responding to: ???'s previous message |
I use 74LVC4245 NXP, TI and probably others.
why use discretes whern a cheap chip exist. Yes, the circuit is, indeed, 'cute', now somebody please tell me what the propagation delay is for all 4 cases. Erik |

| 74LVC4245 is not "automatically" bidir... | 01/01/70 00:00 | |
| 74LVC4245 has 24 leads | 01/01/70 00:00 | |

| What! | 01/01/70 00:00 | |
