Description

MAX3222ECAP is a dual RS-232 transceiver from Maxim. It provides two drivers and two receivers to connect a microcontroller’s UART to RS-232 devices.
Key points
- Function: Converts TTL/CMOS UART signals to RS-232 levels and RS-232 inputs back to TTL/CMOS.
- Supply and operation: Single-supply device (typically 3.0–5.5 V) using a charge-pump to generate RS-232 voltages.
- ECAP note: The ECAP suffix indicates external charge-pump capacitors are required (C1+, C1−, C2+, C2−, plus V+ and V− connections per datasheet).
- Pinout (typical): T1IN, T2IN (TTL/CMOS inputs); T1OUT, T2OUT (RS-232 outputs); R1IN, R2IN (RS-232 inputs); R1OUT, R2OUT (TTL/CMOS outputs); V+, V− (pump outputs); VCC and GND.
- Applications: MCU-to-PC serial ports, embedded UART interfaces, debugging consoles.
In short, MAX3222ECAP is a robust, dual-channel bridge between a microcontroller and RS-232 devices, requiring external pump capacitors.

Features

Here are the typical features of MAX3222ECAP (RS‑232 transceiver with ECAP package):
- 2 drivers and 2 receivers for RS-232 communication
- Single-supply operation: 3.0 V to 5.5 V
- Internal charge-pump with external capacitors (typical 0.1 µF) to generate RS-232 levels
- ECAP package (exposed pad) for improved thermal dissipation
- TTL/CMOS-compatible logic thresholds on inputs and RS-232-compatible outputs
- Low quiescent current and suitable for low-power applications
- Wide operating temperature range (common variant: -40°C to +85°C)
- ESD protection on RS-232 lines and control pins
- Input/output voltage ranges suitable for RS-232 signaling and standard interfaces
Note: Check the exact datasheet for cap values, temperature range, and package details for the specific lot.

Package

An 8-pin SOIC package with an exposed pad (EP) for thermal relief.

Pinout

- Pin count: 16 pins (DIP-16/SO-16/TSSOP-16 variants; ECAP packaging variant also 16 pins).
- Function: Dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS logic levels to RS-232 levels and RS-232 levels to TTL/CMOS. Requires external charge-pump capacitors (C1+/C1−, C2+/C2−, plus V+ and V−).

Manufacturer

Manufacturer: Maxim Integrated Products (now part of Analog Devices).
