概述

Description

The MAX3488ESA+T is a Maxim RS-232 transceiver (part of the MAX3488 family). It provides the level-shifting between TTL/CMOS logic and RS-232 signals, allowing a microcontroller or ASIC to talk to RS-232 devices. Key features typically include an on‑chip charge pump to generate the required RS-232 voltage rails from a single supply, low power consumption, and one or more transmitters/receivers with 3-state outputs for bus sharing. The ESA suffix usually denotes an RoHS/lead‑free, extended‑temperature package, while +T indicates Tape & Reel packaging for automated assembly. It’s commonly used to connect microcontrollers to PC/modem serial ports and other RS-232 links. For exact channel count, voltage ranges, baud capability, and pinout, consult the latest datasheet.

Features

Here are the typical features you’d expect for the MAX3488ESA+T (RS-485/RS-422 transceiver family), in concise form:
- 8 differential RS-485/RS-422 transceiver channels in one device (per-channel TX/RX).
- Single-supply operation: 3.3 V to 5.5 V (wide supply range).
- Up to about 10 Mbps data rate per channel (RS-485 standard speed range).
- 1/8 unit load on the bus (allows many devices on a single network).
- Fail-safe receivers: RO goes high when inputs are open, shorted, or idle.
- Per-channel control: DE (driver enable) and /RE (receiver enable) for each channel.
- Common-mode range suitable for RS-485 bus (-7 V to +12 V typical).
- Bus-pin protection with ESD protection on A/B lines.
- Low quiescent power; optional sleep/standby modes.
- Extended-temperature version available (ESA) for -40°C to +85°C environments.
- Packaging: Tape & Reel (+T) option.
Note: exact electrical specs (e.g., max data rate, IOL, fault protection levels) vary by revision; consult the specific MAX3488ESA+T datasheet for precise figures.

Package

MAX3488ESA+T uses an 8-pin surface-mount package (SOIC). The “+T” denotes Tape & Reel packaging.

Pinout

- Pin count: 8 pins
- Function: RS-485/RS-422 transceiver (half‑duplex). Provides:
- A and B differential bus pins
- DI (data in) and RO (data out)
- DE (driver enable) and RE (receiver enable)
- VCC and GND
- ESA indicates the 8‑pin SOIC package; +T = tape-and-reel.

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices). What kind of company: a global fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits (ICs).

Application

Industrial automation and control (PLC, motor drives, sensors); building automation (HVAC, lighting); process control and telemetry; data acquisition and remote I/O; multi-point RS-485/RS-422 differential networks; long-distance, noise-robust serial communication.

Equivalent

Equivalent RS-485/RS-422 transceivers (non-isolated) from other vendors:
- TI: SN65HVD178x family (e.g., SN65HVD178, SN65HVD232)
- STMicroelectronics: SP3482, SP3485, SP3486
- Analog Devices: ADM485, ADM2483
If isolation is needed, consider ADI ADM248x family or TI ISO transceivers.
