LTC4300A-3IMS8#PBF 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 VCC2 power_in Card-side supply voltage (2.7V to 5.5V). Provides supply for the card I2C bus pull-ups on SDAOUT and SCLOUT. Bypass with at least 0.01uF close to this pin.
2 SCLOUT bidirectional Serial clock output to the card-side I2C bus. Connects through the bidirectional buffer to SCLIN on the backplane side; requires an external pull-up to VCC2.
3 SCLIN bidirectional Serial clock input from the backplane-side I2C bus. Connects through the bidirectional buffer to SCLOUT on the card side; requires an external pull-up to VCC.
4 GND power_in Device ground. Connect to a ground plane for best performance.
5 ENABLE input Digital CMOS-threshold enable input (thresholds 0.1VCC to 0.9VCC). Grounding places the part in a low current mode (disables rise-time accelerators, precharge, and isolates card from backplane); drive to VCC for normal active operation. ENABLE is VCC-referenced; do not tie to VCC2.
6 SDAIN bidirectional Serial data input from the backplane-side I2C bus. Connects through the bidirectional buffer to SDAOUT on the card side; requires an external pull-up to VCC.
7 SDAOUT bidirectional Serial data output to the card-side I2C bus. Connects through the bidirectional buffer to SDAIN on the backplane side; requires an external pull-up to VCC2.
8 VCC power_in Main input power supply from the backplane (2.7V to 5.5V). Provides supply for the backplane-side I2C bus pull-ups on SDAIN and SCLIN. Bypass with at least 0.01uF close to this pin.
