Product Description
STMicroelectronics ST26C31BDR is a high-performance 4-channel line transmitter IC engineered to provide reliable differential signal transmission, particularly for RS-422 communication interfaces. Designed with both CMOS and TTL logic compatibility, the device is well-suited for a wide array of industrial, commercial, and embedded system applications.
Each channel operates independently, allowing engineers to transmit multiple signals with excellent signal integrity. The line driver delivers differential outputs, which are essential for noise immunity and robust operation in electrically noisy industrial environments.
The IC is packaged in a compact 16-pin SOIC format, making it easy to integrate into surface-mount PCB designs. The supply voltage flexibility - from 4.5V to 5.5V - ensures compatibility with varied system voltages, while the low typical supply current (2mA) minimizes power consumption, an important factor in large-scale deployments and energy-sensitive designs.
Electrical parameters include a maximum high level output current of -20mA and a low level output current of 20mA, ensuring robust interfacing with downstream components. Data propagation delay is kept low (11ns typical), supporting high-speed data communication requirements.
The device is designed for operation from -40°C to 85°C, enabling deployment in demanding industrial and laboratory environments. Its differential output and TTL input architecture support reliable transmission of digital signals across extended cable lengths, making it suitable for RS-422 and similar line interface IC applications.
Applications include industrial automation, laboratory instrumentation, communication equipment, embedded systems, and manufacturing environments where secure, high-speed signal transmission is required. The ST26C31BDR's SOIC package further optimizes assembly for production environments.
Supports four independent channels for versatile signal transmission. Operates with CMOS/TTL logic inputs for maximum system compatibility. Differential output type ideal for RS-422 interfaces. 16-pin SOIC surface mount package streamlines PCB integration.
Wide supply voltage (4.5 - 5.5V), low supply current (2mA). Fast propagation delay (11ns), robust output currents (-20mA/20mA). Industrial-grade temperature range (-40°C to 85°C). Ideal for high-speed industrial data transmission.
