Descripción general

Description

MAX253CUA+ is a Maxim Integrated dual RS-232 transceiver. It provides two drivers and two receivers to connect a microcontroller’s UART to RS-232 devices (PCs, modems, GPS, etc.).
Key points
- Single-supply operation from about 3.0 to 5.5 V.
- Uses a charge-pump to generate RS-232 voltage levels from the logic supply.
- TTL/CMOS-compatible logic inputs and RS-232-level outputs; supports two independent TX/RX channels.
- Features typically include enable/shutdown control and standard UART data-rate support (high enough for common serial speeds; check datasheet for exact limits).
- Available in small packaging (e.g., 8-pin small-outline variants) and RoHS-compliant options.
Usage
- Ideal for MCU-to-RS-232 bridging in embedded systems and serial peripherals.
Note
- For exact electrical specs, capacitor needs for the charge pump, pinout, and maximum data rate, consult the current MAX253CUA+ datasheet and package variant.

Package

MAX253CUA+ is available in an 8-pin SOIC (Small-Outline) package; it’s the RoHS lead-free variant.

Pinout

- Pin count: 16 pins (16-pin package such as SOIC/TSSOP).
- Function: Dual RS-232 transceiver (two drivers and two receivers) with an onboard charge-pump voltage converter; interfaces TTL/CMOS logic to RS-232 levels and requires external capacitors to generate ± voltages; single-supply operation (typically 3V–5.5V).

Manufacturer

MAX253CUA+ is made by Maxim Integrated Products, Inc., a semiconductor company that designs and sells analog and mixed-signal integrated circuits (Maxim is now part of Analog Devices).

Application

RS-232 transceiver for MCU-to-RS-232 serial interfaces. Applications include:
- PC/modem/serial printer connections
- Data acquisition systems
- Industrial controllers/PLCs
- Instrumentation and test equipment
- Point-of-sale terminals
- Telecom peripherals

Equivalent

MAX253CUA+ is a dual RS-232 transceiver with charge-pump. Common equivalents:
- Analog Devices: ADM232 / ADM232A
- Renesas/Intersil: ISL232x
- Exar: SP3232E (pin-compatible RS-232 transceiver)
