Analog Devices Inc Maxim Integrated · Ethernet Transceivers · SOIC-8
MAX3444EASA+T from Analog Devices Inc Maxim Integrated, in a SOIC-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 | VCC | power_in | Positive power supply; rated +4.75V to +5.25V. |
| 2 | TXD | input | J1708 transmit input; logic-low drives A and B to dominant state, logic-high to recessive state. |
| 3 | GND | power_in | Ground reference. |
| 4 | DE | input | Driver enable control input; pull low to enable driver output on A and B, pull high for high-impedance output. |
| 5 | RE | input | Receiver enable control input; pull low to enable receiver output RO, pull high to disable or for shutdown mode. |
| 6 | RO | output | Receiver output; high when (A−B) ≥ −50mV and receiver enabled, low when (A−B) ≤ −200mV and receiver enabled. |
| 7 | A | tri_state | Noninverting differential bus line for J1708/RS-485 communication; driven by driver when enabled, received by receiver, or high-impedance when disabled; withstands ±60V fault protection. |
| 8 | B | tri_state | Inverting differential bus line for J1708/RS-485 communication; driven by driver when enabled, received by receiver, or high-impedance when disabled; withstands ±60V fault protection. |
