Description

MAX3081ECSA+T is a single-channel RS-232 transceiver from Maxim Integrated. It provides a TTL/CMOS UART interface on one side and RS-232 level signals on the other, enabling a microcontroller to talk to RS-232 devices.
Key points
- Interface: 1 driver and 1 receiver for RS-232 signaling
- Supply: operates from 3.0 V to 5.5 V
- Temperature: extended range (-40°C to +85°C)
- Internal charge pump to generate RS-232 voltage levels
- Packaging: E = extended temp, CSA = package variant, +T = Tape-and-Reel
- Applications: microcontroller to PC serial ports, data loggers, industrial controllers, modems, etc.
For exact electrical specifications, timing diagrams, pinout, and application notes, refer to the MAX3081ECSA+T datasheet.

Features

Key features of MAX3081ECSA+T (RS-232 transceiver):
- Dual transmitters and dual receivers (2 TX / 2 RX)
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge-pump to generate RS-232 voltage levels
- High-speed data rate suitable for UART interfaces (typical up to Mbps range)
- Low quiescent current with optional power-down/shutdown mode
- TTL/CMOS-compatible input thresholds; RS-232 compliant outputs
- ESD and transient protection on I/O lines
- Extended temperature range (-40°C to +85°C)
- 8-pin package; RoHS-compliant; ECSA lead-free; Tape & Reel (T) packaging variant
Note: Exact electrical specs (speed, currents) are device-dependent; please verify in the datasheet for precise numbers.

Package

An 8-pin SOIC (SOP-8) package; +T indicates Tape & Reel.

Pinout

- Pin count: 16 pins (MAX3081ECSA+T in a 16‑pin package).
- Function: Single‑channel RS‑232 transceiver (one driver and one receiver) with an on‑chip charge pump to generate RS‑232 voltage levels from a single supply; interface between TTL/CMOS logic and RS‑232 lines.
