The SP510E is a highly integrated physical layer solution that is configurable to support multiple serial standards. It incorporates eight drivers and eight receivers (8TX/8RX), configurable for either differential (V.11 or V.35) or single ended (V.28 and V.10) signaling.

SP510E enables a Serial Communications Controller to implement a variety of serial port types including V.24, V.25, V.36, EIA-530, EIA-530-A, X.21, RS-232. The device architecture is designed to support the data and clock signals used in HDLC or SDLC serial ports as either DTE or DCE.

Operating configuration is programmable in system using the mode-select pins. The V.11 and V.35 modes include internal bus termination that may be switched in or out using the TERM_OFF pin. The SP510E is ideal for space constrained applications. It requires only a single 5V supply for full operation. The VL pin determines the receiver output voltage (VOH, down to 1.65V), for interfacing with lower voltage CPUs and FPGAs. For single supply operation at 5V the VL pin will be connected to VCC.

Fully compliant V.28 and V.10 driver output voltages are generated using the onboard charge pump. Special power sequencing is not required during system startup. Charge pump outputs are internally regulated to minimize power consumption. The SP510E requires only four 1µF capacitors for complete functionality. The device may be put into a low power shutdown mode when not in active use.

All receivers have fail-safe protection to put outputs into an output-high state when inputs are open, shorted, or terminated but idle.

ESD is caused by static electricity. In order for an ESD event to occur there must be a buildup of static charge. Very high charge levels are actually quite rare. In a normal factory environment, taking basic ESD precautions (grounding-straps, anti-static smocks, ionizers, humidity control, etc.) static levels can be kept below a few tens of volts. In an uncontrolled environment, like an office, static levels rarely get above 2000 volts. Under some worstcase conditions (wearing synthetic fabrics, rubbing against synthetic upholstered furniture, extremely low humidity)
levels can go as high as 12 to 15 thousand volts. Actually to get to 15000 volts or higher you would need to be in an uncomfortably dry environment (humidity below 10%) otherwise static charge will naturally dissipate through corona discharge. It would definitely be considered a “bad hair day.” Humans can generally feel a static shock only above 3000 volts. A discharge greater than 4000 volts can cause an audible “pop.” But repeated lower level discharges can be imperceptible and still may have a cumulative damaging effect on sensitive ICs. All ICs, even those with robust protection, can be damaged if they are hit hard enough or often enough.

Actually the letter “E” could have two different meanings, depending on where it is in the part number. Most of our interface devices are available in different temperature grades. Commercial temperature (0 to 70C) has a “C” after the numeric part number. Industrial-extended temperature (-40 to +85C) use the letter E. So for example SP485CN is commercial and SP485EN is industrial. The second letter indicates the package type, in this case N for narrow-SOIC. Another E in the suffix indicates that this device has enhanced ESD protection, typically of ±15000Volts on the interface pins. Devices that do not have the enhanced ESD still contain built-in ESD protection of at least ±2000Volts. For example the SP485ECN is ESD rated up to ±15kV, and the SP485CN is rated for ±2kV HBM.

Most ICs in a typical system are at greatest risk of ESD damage in the factory when the PCB is assembled and the system is being built. After the system is put together they are soldered onto the PCB and shielded within a metal or plastic system enclosure. Interface ICs are designed to attach to an external connector that could be exposed to ESD when a cable is plugged in or when a person or object touches the connector. These interface pins are most likely to see ESD exposure and therefore benefit from additional protection.
