MAX202CPW Description

The MAX202CPW from Texas Instruments is a full-duplex RS-232 transceiver designed for reliable serial communication in industrial and embedded systems. Housed in a 16-pin TSSOP package, this surface-mount IC operates within a 4.5V to 5.5V supply range, making it compatible with standard 5V logic. With a data rate of 120Kbps, it supports moderate-speed serial data transmission while maintaining robust signal integrity. The device integrates two drivers and two receivers, enabling bidirectional communication over RS-232 interfaces. Although marked as obsolete, it remains a viable choice for legacy systems due to its proven performance and ROHS3 compliance.

MAX202CPW Features

• Full-Duplex Operation: Simultaneous transmission and reception for efficient data exchange.
• 500mV Receiver Hysteresis: Enhances noise immunity in electrically noisy environments.
• Wide Operating Temperature (0°C to 70°C): Suitable for commercial and industrial applications.
• Low Power Consumption: Optimized for energy-efficient designs.
• RS-232 Protocol Compliance: Ensures compatibility with standard serial communication interfaces.
• Surface-Mount (TSSOP) Packaging: Ideal for space-constrained PCB designs.
• Moisture Sensitivity Level (MSL) 1: Unlimited shelf life under typical storage conditions.

MAX202CPW Applications
