#148151 - 74LVC4245 is not "automatically" bidir... Responding to: ???'s previous message |
...one needs to "tell" the current direction, which is common for all 8 pins.
Read: unusable for e.g. I2C. JW |

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

| none of these are bidir | 01/01/70 00:00 | |

| What! | 01/01/70 00:00 | |
| but the 24 pins don't provide equivalent... | 01/01/70 00:00 | |
| Still less :) | 01/01/70 00:00 | |
