Silicon Diode Array Improves Communication Line Protection

April 2, 2008 12:33 pm | Comments

Littelfuse, Inc. expanded its SP72x Series of SCR diode arrays for electrostatic discharge (ESD) and other over-voltage protection of telecomm and datacom interface circuits. The SP725 is suitable for protection of microprocessor/logic inputs, data bus lines, analog device inputs and many other voltage clamp applications. Its thyristor-based design uses two bipolar SCR/diode structures to protect each of the four inputs (typically external signal or bus lines). Its operation is similar to what is known as a steering diode, but it has lower capacitance and leakage current for a given impulse rating, meaning less chance of communication signal distortion.

Fine Binning for White LEDs Delivers Improvements

April 2, 2008 11:37 am | Comments

SRAM Opto Semiconductors introduced its advanced fine binning for white LEDs that delivers improvements in off-angle color uniformity as well as a typical color rendering index (CRI) of 80+. This advanced binning process for white LEDs corresponds to a 3-step McAdams ellipse, and it is available for Power TOPLED, Advanced Power TOPLED and the proprietary DRAGON family of products. Applications such as backlighting of diffused surfaces and linear array applications benefit from the uniform light enabled by this technology which is fully ANSI/Energy Star-compliant in the United States.

QVGA Modules Feature a Touchscreen Option

April 2, 2008 11:31 am | Comments

Phoenix Display International (PDI), Inc. introduced its line of 5.7" monochrome QVGA modules that are available in FSTN/gray/positive/transflective or STN/blue/negative/transmissive configurations. These graphic modules (PN G-320240-5.7) allow the user to control each pixel individually to display both text and graphics simultaneously. With a variety of options available, the monochrome graphic displays are modular in design, and they can be customized to fit specific applications. Both the STN and FSTN models are available with an RA8803 controller with built-in touchscreen controller, and they can be configured with either a CCFL or LED backlight.
