Manufacturer Part Number

MAX232ECPE

Description

RS232 transceiver IC. Supports full-duplex communication, meaning it sends and receives 2 channels simultaneously. Comes in a 16-pin DIP (Dual In-line Package) for easy through-hole mounting. Ideal for connecting TTL/CMOS logic to RS232 serial ports. This model is obsolete, so quantities are limited to available stock.

Specifications

Supports two transmit channels and two receive channels. Operates at supply voltage between 4.5V and 5.5V. Data transfer rate up to 120Kbps. Receiver input hysteresis is 500mV for noise filtering. Works within a temperature range of 0°C to 70°C. Fits standard DIP sockets (package width 0.300", pitch 7.62mm). Moisture sensitivity level is 1, so it is not sensitive to moisture during manufacturing. RoHS non-compliant but REACH unaffected. Classified under ECCN EAR99 and HTSUS 8542.39.0001.

Device Structure

Plastic 16-pin DIP package. Includes charge pump circuitry for RS232 voltage level conversion. 2 drivers, 2 receivers integrated. Full-duplex signal support.

Performance Characteristics

Provides reliable RS232 voltage conversion and signal integrity for two transmit and two receive lines. 500mV hysteresis reduces errors caused by noisy signals. Achieves up to 120Kbps data rate, suitable for standard serial communication speeds.

Application Environments

Commonly used in computer serial ports, embedded system communication, industrial equipment interfaces, and data communication devices where RS232 signals are needed. Suitable for environments fitting commercial temperature ranges (0°C to 70°C).

Selection Guidelines

Choose this model when you need classic RS232 transceivers, through-hole mounting, operation at 5V, and simple integration into breadboards or standard DIP sockets. Make sure your data rate is under 120Kbps and temperature requirements fall within the commercial range. Since the part is obsolete, check for stock availability or consider alternatives.

Usage Considerations

Not RoHS compliant, so unsuitable for applications needing lead-free components. Ensure the operating temperature matches your environment. Verify supply voltage stays within 4.5V to 5.5V. Mount only in through-hole compatible PCB layouts. No special handling needed regarding moisture sensitivity (MSL 1).
