MAX485ECSA+T

MAX485ECSA+T is Maxim’s low‑power, half‑duplex RS‑485/RS‑422 transceiver in an 8‑pin ECSA package (Tape & Reel option). It combines a differential driver and receiver for microcontroller‑to‑multi‑drop serial networks over twisted pair.
Key points:
- Single‑supply operation (commonly 5V)
- Up to about 2.5 Mbps data rate
- 1/8 unit‑load on the bus
- Fail‑safe receiver: RO goes high if A/B are idle, open, or shorted
- Standard pins: DI (data in), RO (data out), DE (driver enable), /RE (receiver enable), A, B, Vcc, GND
- Low quiescent current; robust ESD protection; wide bus common‑mode range
Typical uses: industrial control, building automation, sensor networks, and other RS‑485 networks requiring a compact, cost‑effective transceiver.
Note: For exact voltage ranges, temperature spec, and pinout of the ECSA package, consult the MAX485ECSA+T datasheet. The +T suffix indicates Tape & Reel packaging.
