Description
The MAX491CSD is an RS-485/RS-422 transceiver from Maxim Integrated (now Analog Devices). It combines a differential line driver and receiver in an 8-pin package for half‑duplex, multi‑point serial links.
Key points:
- Interfaces: DI (data in), DE (driver‑enable), RO (receiver out), /RE (receiver enable), A/B bus lines.
- Features: fail‑safe receiver (RO stays high when the bus is idle/open/shorted), single‑supply operation, bus‑fault protection and ESD protection, low power.
- Use cases: industrial networks, building automation, data acquisition, and any multi‑drop RS‑485/RS‑422 link.
- Packaging: CSD suffix denotes a specific package/variant in Maxim’s lineup; see the datasheet for exact pinout and electrical specs.
For precise electrical characteristics (data rate, voltage range, protection levels), consult the MAX491CSD datasheet.

Equivalent
I need the chip’s function to give exact cross-refs. MAX491CSD could be an RS-232, RS-485/RS-422 transceiver, etc., with specific voltage and package. Please share the datasheet or confirm: 1) interface (RS-232 or RS-485/422), 2) supply (3.3V/5V) and package. With that, I’ll list direct equivalents from TI, Analog Devices, ON Semiconductor, etc., concise one-liners.
Pinout
- Pin count: 8 pins (8‑pin package, e.g., SOIC‑8/TSSOP‑8).
- Function: High‑side load switch. It connects VIN to VOUT to power a load, with enable control (EN), current‑limit protection, and overcurrent/thermal protection. It uses pins for VIN, VOUT, EN, GND, and current‑limit setting.
