COSMAX13487EESA

COSINE · RS-485 / RS-422 ICs · SOP-8

COSMAX13487EESA from COSINE, in a SOP-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 RO output Receiver output. When receiver is enabled (RE low), RO is high if A-B > +200 mV and low if A-B < -200 mV. High-impedance when RE is high or in shutdown.
2 RE input Receiver output enable, active low (hot-swap input). A low enables the receiver output RO; a high lets the internal auto-direction circuit control the receiver.
3 SHDN input Shutdown, active low. Drive SHDN low to put the device into shutdown mode (<10 µA); drive high for normal operation.
4 DI input Driver input. Low forces A low and B high; high forces A high and B low. Also feeds the internal state machine that auto-enables/disables the driver; must be held high in idle.
5 GND power_in Ground reference (0 V).
6 A bidirectional Non-inverting RS-485/RS-422 bus pin: non-inverting receiver input and non-inverting driver output. ±15 kV HBM ESD protection; withstands -7 V to +12 V common-mode range.
7 B bidirectional Inverting RS-485/RS-422 bus pin: inverting receiver input and inverting driver output. ±15 kV HBM ESD protection; withstands -7 V to +12 V common-mode range.
8 VCC power_in Power supply, 3.0 V to 5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor. Quiescent current ~700 µA typ.

Provenance

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

  • Datasheet: COSINE datasheet (14 pp, sha256 cf855f03e34f9b22, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
