LTC4313IMS8-3#PBF

Analog Devices · Signal Buffers, Repeaters, Splitters · MSOP-8

LTC4313IMS8-3#PBF from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ENABLE input Connection enable input; low isolates SDAIN/SCLIN from SDAOUT/SCLOUT, asserts READY low and disables rise time accelerators, high connects the buses after a stop bit or bus idle is detected; connect to VCC if unused (10k to GND for staggered-pin Hot Swap).
2 SCLOUT bidirectional Serial bus 2 clock input/output, connected to the SCL segment where stuck low recovery is desired, needs an external pull-up and must not be left open.
3 SCLIN bidirectional Serial bus 1 clock input/output connected to the upstream SCL line, needs an external pull-up (bus supply need not be ≥ VCC for the LTC4313-3) and must not be left open.
4 GND power_in Device ground.
5 READY output Open-drain N-channel connection ready status output that pulls low when input and output sides are disconnected, typically pulled up with 10k to the bus supply, and may be left open or tied to GND if unused (absolute max 6V, 50mA sink).
6 SDAIN bidirectional Serial bus 1 data input/output connected to the upstream SDA line, needs an external pull-up (bus supply need not be ≥ VCC for the LTC4313-3) and must not be left open.
7 SDAOUT bidirectional Serial bus 2 data input/output, connected to the SDA segment where stuck low recovery is desired, needs an external pull-up and must not be left open.
8 VCC power_in Power supply input from 2.9V to 5.5V, bypass with at least 0.01µF to GND.
