TVs Tube devices can be divided into unipolar and bipolar by polarity, i.e. unidirectional TVs and two-way TVs tubes.One-way TVs tube protection devices can only protect positive or negative pulses, while the bidirectional TVs tube protection device is connected to a protected line, one end of the ground, whether from the reverse or from the positive ESD pulse is released, more effectively protect the IC.The forward characteristic of unidirectional
description of the Extreme Lite system (Ramos dedicated) (FAQ)For Ramos-er, the only purpose of system streamlining is to Ramos, and streamlining is only for Ramos. I prefer to hear the use of a streamlined system for Ramos, which should be his main battleground.

A : If the integration of the USB3.0 drive, some motherboards may appear blue screen problems, in order to stabilize, or not integ

Texas Instruments have a wide range of RS-485 transceiver products. Features of the device include low EMI, low power (1/8UL), high ESD Protection (from 16kV to 30kV), and a full set of fault insurance functions for open circuit, short circuit, and bus idle conditions. For long-range applications that require isolation, Texas Instrument's product line also extends to single-chip dual-isolating, three-isolating, and four-isolating one-way and

The SVN version of The stadict-3.0.2 solves the bug of compiling errors in GCC 4.3, and adds some new features, such as the Global hotkey. In addition, because gnome2.24 does not have esound, it cannot make people sound, I have modified the source code by referring to other methods on the Internet and added so

Interface protection: ESD protection.
Power supply protection: Dual-overcurrent protection.
Operating System: common operating systems are supported, and independent drivers are not required.
Work instruction: Interface Activity instruction and port operation instruction.
Operating temperature:-40 ℃ ~ 85 deg C industrial level.
Why isolate USB interfaces?

This is a test that only makes sense for smart cards and is used to check the robustness of the chip against electrostatic discharge ESD (electrostatic discharge, A 100pf capacitor is charged to ± 1500v sequentially and discharged to different contacts of the chip through a 1500 Ω throttling resistor. Because these discharges must not endanger the functions of the chip and do not change the content of the memory.

line), and conductive interference is through the power line or signal line and other lines, the interference energy is directly coupled or injected into DUT or line. The type of disturbance energy includes two types: continuous wave and transient wave, which are divided into two coupling modes: radiation and conductivity. The anti-disturbance test method can be subdivided into four categories: continuous wave transmission, continuous wave radiation, transient conduction (transiet) and electros

Io expansion: Because the smallest system board is used here, I/O is not processed too much. I/O is cited as a double-row plug-in as much as possible to facilitate subsequent expansion.

attenuation of signals in cable transmission. It is a key parameter that determines the available bandwidth.
External Noise
Noise enters the channel through external electromagnetic fields near the channel. Non-Direct electrostatic discharge (ESD) or fast current transient (EFT) is one of the external noise sources.
In the cabling system of the company, products with excellent balancing performance solve this noise problem. Balancing is the degree to
