SN751701PS Description

The SN751701PS from Texas Instruments is a half-duplex RS-232 transceiver designed for reliable serial communication in industrial and embedded systems. Housed in an 8-pin SOIC surface-mount package, this IC integrates one driver and one receiver, making it ideal for compact designs requiring bidirectional data transmission. Operating over a wide supply voltage range (4.5V to 15V), it ensures compatibility with diverse power rails while delivering robust performance in noisy environments. With 600 mV of receiver hysteresis, the device excels in rejecting signal noise, enhancing data integrity. Its RoHS3 compliance and MSL 1 (Unlimited) rating further underscore its suitability for modern, environmentally conscious manufacturing.

SN751701PS Features

• Half-Duplex RS-232 Transceiver: Supports bidirectional communication with a single channel.
• Wide Voltage Range (4.5V–15V): Flexible power supply options for varied system requirements.
• High Noise Immunity: 600 mV receiver hysteresis minimizes errors in electrically noisy environments.
• Surface-Mount Design (8-SOIC): Compact footprint for space-constrained PCB layouts.
• Robust Protocol Compliance: Fully adheres to RS-232 standards, ensuring interoperability.
• Last-Time-Buy Status: Available for legacy system support, though newer alternatives may be recommended for future designs.

SN751701PS Applications

The SN751701PS is particularly suited for:

• Industrial Automation: Reliable serial communication in PLCs, motor controllers, and sensor interfaces.
• Embedded Systems: Low-power, noise-resistant data transmission in microcontroller-based designs.
• Legacy Equipment Upgrades: Replacement or repair of aging RS-232 interfaces in medical, telecom, or test equipment.
• Battery-Powered Devices: Efficient operation across a broad voltage range supports portable applications.

Conclusion of SN751701PS

The SN751701PS stands out for its noise resilience, wide voltage tolerance, and compact form factor, making it a pragmatic choice for half-duplex RS-232 applications. While its Last-Time-Buy status indicates phased availability, its performance in harsh environments and adherence to industry standards ensure continued relevance in legacy and niche systems. Engineers should evaluate newer TI alternatives for forward-looking designs but can rely on this transceiver for proven, stable operation in existing setups.
