SP481E and SP485E are a group of half-duplex transceivers, and the interface integrated circuit SP485EEN conforms to the specifications of RS-485 and RS-422 serial protocols and has better ESD performance. Improve the ESD tolerance of Human Body Model and IEC61000-4-2 exhaust air to more than ±15kV. Interface IC SP485EEN These devices are pin-compatible with MaxLinear's SP481 and SP485 devices as well as popular industry standards. Interface IC SP485EEN Like the original version, the SP481E and SP485E use Maxlinear's BiCMOS design to achieve low-power operation without sacrificing performance. SP481E and SP485E can meet the requirements of RS-485 and RS-422 protocols under load, up to 10Mbps. SP481E is equipped with a low power shutdown mode

SP481E and SP485E are half-duplex differential transceivers, and the interface integrated circuit SP485EEN meets the requirements of RS-485 and RS-422. Manufactured on Maxlinear's patented BiCMOS process, the product requires a fraction of the power of older bipolar designs. The RS-485 standard is ideal for multidrop applications and remote interfaces. RS-485 allows up to 32 drivers and 32 receivers to be connected to one data bus, making it ideal for multi-drop applications. With cable lengths up to 4,000 feet, RS-485 transceivers feature a wide (-7V to 12V) common-mode range to accommodate ground potential differences. Since RS-485 is a differential interface, the data is almost immune to noise in the transmission line.

The driver outputs of the drivers SP481E and SP485E are differential outputs that meet the RS-485 and RS-422 standards. Typical no-load output voltage fluctuations are 0 volts to 5 volts. In the bad case of loading the entire differential output of 54?, the driver can maintain a voltage level greater than 1.5V. The drivers for the SP481E and SP485E have an active high enable control line. A high DE (pin 3) logic will enable the differential driver output. A logic low on DE (pin 3) will tri-state the driver output. The SP481E and SP485E transmitters will run at least 10Mbps.

The SP481E and SP485E receivers have differential inputs with input sensitivity as low as ±200mV. The input impedance of the receiver is typically 15 kΩ (12 kΩ minimum). The wide common-mode range of -7V to +12V allows for large ground potential differences between systems. The receivers of the SP481E and SP485E have a three-state enable control pin. A logic low on RE (pin 2) will enable the receiver and a logic high on RE (pin 2) will disable the receiver. The receiver of the SP481E and SP485E will run at least 10Mbps. The receivers of both devices are equipped with fail-safe features. Fail-safe guarantees that the receiver output will be in a high state when the input is not connected.
