The SP485ES-L is an ideal device for interfacing high speed, low-power TTL / CMOS asynchronous data transmission on multipoint bus networks. It is part of a family of RS-485/RS-422 transceivers specially designed for use in multipoint applications. These devices are typically used in data communications systems and are suitable for both full-and half-duplex applications.

The SP485ES-L incorporates two receivers and one driver, allowing for both full-and half-duplex communications. The driver can operate at data rates of 40 Mbits/s, making it ideal for high-speed data communications. Its low-power operation and ESD protection makes it suitable for use in systems where power conservation and reliability are important.

The SP485ES-L features an on-chip, selectable slew-rate limiting driver which reduces EMI and π-network bypass capacitors to reduce signal reflection in applications with high baud rate and long cables. The device is interfaced through the industry-standard RS-485/RS-422 compatible BUS interface ports.

The SP485ES-L offers various features designed to make it compatible with various data transmission protocols. It supports data format of 8-or-9 bit UART or asynchronous data, with variable baud-rates. The driver is also enabled for two modes of operation: transmitter mode or receiver mode. In the transmit mode, the device can send asynchronous data with variable baud rates up to 40 Mbits/s over long lines. In the receive mode, the SP485ES-L can detect differential signals with up to 40 Mbit/s data rates.

The SP485ES-L includes a number of advanced features that make it suitable for applications in a wide variety of data communication networks. It supports data transfer protocols such as ARINC 429 and MIL-STD 1553. It also supports various error detection and correction schemes such as 8-bit checksum, cyclic redundancy checks (CRC), and parity check.

The SP485ES-L also features a built-in fault-tolerant programming interface which enables it to support multiple-host devices and communication networks. It also features a 15 kV ESD protection, integrated power-down control, temperature monitoring, and an error LED that indicates an error status in the transmitter or receiver.

The SP485ES-L is used in a variety of applications, including industrial automation, mobile robots, medical equipment, point-of-sales systems, and military applications. Its compatibility with both the RS-485 and RS-422 standards makes it ideal for a variety of systems in which multiple nodes need to communicate with each other. Its high-speed and low-power operation make it suitable for long-distance communication networks.
