LTC4307IMS8#TRPBF from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ENABLE | input | Active-high connect enable. Driving ENABLE high allows the LTC4307 to connect SDAIN/SCLIN to SDAOUT/SCLOUT after a stop bit or bus idle; driving low breaks the connection. Threshold ~1.4V, input current ~0.1µA. |
| 2 | SCLOUT | bidirectional | Output (card-side) side of the buffered I2C/SMBus clock line. Open-drain, connects to SCLIN when ENABLE is high and bus is idle. Precharged to ~1V; used to generate up to 16 recovery pulses when a stuck bus is detected. |
| 3 | SCLIN | bidirectional | Input (backplane-side) side of the buffered I2C/SMBus clock line. Open-drain, precharged to ~1V, high-impedance when VCC = 0V. Logic threshold ~0.55·VCC. |
| 4 | GND | power_in | Device ground reference. All voltages referenced to GND. |
| 5 | READY | output | Open-drain status output that pulls low until the backplane and card sides are connected (bus buffer engaged). Requires an external pull-up; VOL ≤ 0.4V at 3mA sink. |
| 6 | SDAIN | bidirectional | Input (backplane-side) side of the buffered I2C/SMBus data line. Open-drain, precharged to ~1V, high-impedance when VCC = 0V. Logic threshold ~0.55·VCC. |
| 7 | SDAOUT | bidirectional | Output (card-side) side of the buffered I2C/SMBus data line. Open-drain, connects to SDAIN when ENABLE is high and bus is idle. VOS ≈ 60mV (100mV max) versus SDAIN when driven low. |
| 8 | VCC | power_in | Positive supply, 2.3V to 5.5V. Bypass with 0.01µF to GND close to the pin. ICC ≈ 8mA typical. |
