In addition, it is compliant with IEC-61000-4-2 requirements for ESD protection, with up to 6-kV protection in contact discharge mode. The device comes in the following functions: differential driver and receiver, differential transceiver, single driver, single receiver, and single transceiver.

SP336ECY-L/TR Application Field

The SP336ECY-L/TR is suitable for multiple applications, such as industrial and instrumentation automation, factory automation, transportation, medical, and security systems. In telecommunication, the device is used in T1/E1 transceiver systems and computer modem backplanes. Furthermore, its usage in automotive is for CAN systems and RS-485 networks. Thanks to its extended voltage range, it can be used in a variety of systems.

SP336ECY-L/TR Working Principle

The SP336ECY-L/TR is designed with an ESD protection circuit, operating in full-duplex mode. It consists of two differential drivers, two differential receivers, and one differential transceiver. The transceiver can be configured with a single driver or a single receiver to provide full-duplex communication with RS-485 and RS-422 compliant systems. The differential drivers are enabled by the driver enable pin (DEn), while the differential receiver is enabled by the receiver enable pin (REn).

The driver and receiver inputs and outputs comply with the RS-485 and RS-422 standard, respectively. The outputs of the transceivers are protected against overvoltage transients up to 15 V, and the receivers are protected against noise transients up to 1.8 mA. The device is capable of continuous data transmission rates up to 1 Mbps, while its extend voltage range allows it to transmit data at speeds up to 10 Mbps.
