Device Structure

Contains multiple RS232 line drivers and receivers on a single chip. Supports full duplex transmission. Built with integrated protection circuitry for over-voltage and ESD. Surface-mount configuration for easy PCB assembly.

Performance Characteristics

High-speed data transmission up to 1 Mbps. Wide supply voltage range allows flexible design. Enhanced noise immunity due to 500 mV receiver hysteresis. Reliable operation across industrial temperature ranges. Low power consumption compared to older designs.

Application Environments

Used in industrial communication systems, PCs, embedded systems, data acquisition equipment, serial data interface boards. Suitable for environments requiring robust serial communications over RS232 standard in harsh temperature ranges.

Selection Guidelines

Choose for designs needing multi-channel RS232 transmission, high data rates, wide supply voltage range, and full duplex operations. Good fit for surface mount assemblies and space-constrained devices. Ensure the number of drivers/receivers and voltage specs meet your system requirement.

Usage Considerations

Verify supply voltage and temperature specs match your application. Surface-mount package needs proper PCB pad layout. Consider power dissipation if operating at maximum data rates. Use recommended ESD handling precautions during assembly.
