See below for comparisons. Even though RS is a very old standard first standardized in it is still popular because it is:. Typical data rates are baud, baud, High data rate RS devices are available up to 1Mbps. Faster speeds are uncommon. This requires an onboard charge pump to generate signals from a single power-supply chip or else multiple positive and negative supply rails.
All signals are unidirectional and the charge pump requires several pins and external capacitors. So small footprint is difficult to achieve. Cables and connectors use more pins and wires than most modern serial protocols. Signals go from one driver to one receiver. RS does not support bi-directional signals or multiple drivers or receivers.
RS uses single-ended signals which makes it difficult to support long cables. Typical RS cables are only about 10 meter or less. High speed 1Mbps are typically less than 1 meter. The wide driver signal swing makes crosstalk a problem. Unbalanced signals with a shared ground reference are less able to withstand ground shifts between driver and receiver.
The wide signal swing takes quite a bit of power. However some of the most commoditized devices lack any shutdown function. Longer runs are possible with some careful system optimization. RS can be used to build multidrop networks with many transmitters and many receivers. On twisted-pair cables a noise signal will couple equally to both wires in the pair and be ignored by the differential receiver.
RS is found mainly in industrial, telecom and commercial applications and is not as widespread in the consumer. Therefore it is not seen as often as RS Also the RS protocol standard defines only the electrical characteristics of the interface. The physical and logical implementations are left up to the user.
Different connectors, different methods for bus-arbitration and data framing all exist under a wide variety of implementations. RS has also been used as the foundation for many proprietary or semi-proprietary standards. Therefore interoperability between RS based interfaces is not always as simple as with RS How much ESD voltage could a part see in normal use? 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. In an uncontrolled environment, like an office, static levels rarely get above volts.
Under some worstcase conditions wearing synthetic fabrics, rubbing against synthetic upholstered furniture, extremely low humidity. All ICs, even those with robust protection, can be damaged if they are hit hard enough or often enough. Why are some pins protected to higher ESD levels than others? 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. Others do not.
What does the E mean? Most of our interface devices are available in different temperature grades. The best way to determine this is to go to maxlinear.
