MAX3444EASA+T

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.
