Description
MAX3488ESA+T is a Maxim RS-485/RS-422 transceiver (half‑duplex) that lets a microcontroller talk to a differential serial bus. It provides a driver input (DI) and a receiver output (RO) plus independent DE/RE enables to control transmit/receive. It operates from a single supply (commonly 3.3 V to 5.5 V) and supports data rates up to several Mbps. The device includes receiver failsafe so RO remains high when the bus is idle or open and features robust bus protection/ESD on the A/B lines. The ESA suffix denotes extended temperature range, and +T indicates Tape & Reel packaging for manufacturing. Typical uses include industrial automation, PLCs, building automation, and other RS-485/RS-422 multi-drop networks. For exact electrical specs (voltage range, data rate, propagation delay, and enable logic), refer to the datasheet.
Equivalent
MAX3488ESA+T is an 8-channel RS-485/RS-422 transceiver (non-isolated) with extended temperature rating. Cross equivalents from other vendors (same channel count, non-isolated) include TI SN65HVD88x family and ST SP348x family. Exact part depends on supply voltage (3.3V/5V) and packaging (DIP/SOIC/T&R). For a precise cross, use a distributor cross-reference tool (e.g., Digi-Key, Mouser) with your voltage and temp requirements.
Features
Key features of MAX3488ESA+T (RS-485/RS-422 transceiver):
- One driver and one receiver (half‑duplex RS-485/RS-422)
- Single-supply operation at 5V
- Industrial temperature range: -40°C to +85°C (ESA)
- Data rate up to about 5 Mbps
- Low quiescent current; available shutdown mode for ultra-low power
- Three-state outputs; separate DE (driver enable) and RE (receiver enable) controls
- Fail-safe receiver: RO output goes high with open, shorted, or idle bus
- Bus-pin ESD protection and rugged I/O protection
- 8-pin package; RoHS-compliant; Tape & Reel option (-T)
Note: Always check the latest datasheet for exact electrical specs and packaging details.

Pinout
- Pin count: 8 pins
- Function: One-channel RS-485/RS-422 transceiver. It includes a differential driver and receiver with pins DI (data in), RO (data out), DE (driver enable), RE (receiver enable, typically active low), A and B (bus lines), Vcc and GND. DE enables the driver to drive A/B; RE enables the receiver to present RO. Suitable for half-duplex RS-485 or RS-422 networks depending on wiring.
