MAX3485EBN

XBLW · RS-485 / RS-422 ICs · DIP-8

MAX3485EBN from XBLW, in a DIP-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 RO output Receiver output: when RE is low, RO is high if A-B ≥ 200mV and low if A-B ≤ -200mV.
2 RE input Receiver output enable (active low): low enables RO, high puts RO in high-impedance, and RE high with DE low enters low-power shutdown mode.
3 DE input Driver output enable: high enables the driver outputs, low puts them in high-impedance, and DE low with RE high enters low-power shutdown mode.
4 DI input Driver input: with DE high, a low on DI forces non-inverting output A low and inverting output B high, while a high on DI forces A high and B low.
5 GND power_in Ground.
6 A bidirectional Non-inverting receiver input and non-inverting driver output (bus limits -8V to +13V).
7 B bidirectional Inverting receiver input and inverting driver output (bus limits -8V to +13V).
8 VCC power_in Power supply input; operating range 3.0 to 5V, absolute maximum +7V.

CAD (KiCad official)

  • Symbol: MAX3485EBN
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: DIP-8 (KiCad packages3D, STEP)
  • 3D model files: max3485ebn-etched.step / max3485ebn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max3485ebn.step / max3485ebn.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: XBLW datasheet (13 pp, sha256 e372cb4a2b51c797, retrieved 2026-10-14, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
