Overview

Description

MAX3218CAP+T is a Maxim RS-232 transceiver (multi-channel) that translates TTL/CMOS UART signals to RS-232 voltage levels and back. The CAP suffix indicates it requires external charge‑pump capacitors (per the datasheet) to generate the RS‑232 swings. The +T suffix denotes Tape‑and‑Reel packaging. Typical use is microcontroller/CPU UART-to-serial port interfacing (PCs, modems, etc.). It contains one or more TX/RX channels (check the datasheet for the exact channel count and pinout) and an internal charge pump, allowing operation from a single supply (commonly 3.3–5.5 V) with RS‑232 level outputs. When implementing, follow the recommended circuit, connect the external caps (C1+, C1−, C2+, C2−) as specified, and observe proper bypassing and ESD considerations. For precise specs (number of channels, data rates, and electrical characteristics), consult the datasheet and the “CAP+T” packaging notes.

Package

MAX3218CAP+T uses a 16-pin package; the “-T” suffix indicates Tape & Reel (packaging).

Pinout

- Pin count: 16 pins (DIP-16/SO-16; Tape & Reel packaging indicated by the “T” suffix).
- Function: Dual RS-232 transceiver (two drivers and two receivers) with an internal charge-pump to generate RS-232 voltages from a single 5V supply; TTL/CMOS side to RS-232 side and vice versa. Requires four external capacitors (C1+/C1−, C2+/C2−).

Manufacturer

- Manufacturer: Maxim Integrated Products (now part of Analog Devices).
- What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (ICs), including interface/communication ICs, power management, data converters, and related products.

Application

Applications of MAX3218CAP+T:
- Embedded systems and microcontroller RS-232 interfaces
- Industrial automation, data acquisition, instrumentation
- Telecom/network equipment (modems, console ports)
- Point-of-Sale systems and printers
- Test, measurement, and lab equipment
- Battery-powered or space-constrained devices needing low-power RS-232 links
