One intermediate shale used for parallel interfacing is the Programmable Peripheral Interface (PPI) 8255. This flake is manufactured by Intel Corporation and packaged in the form of a 40 pin dual in line package and designed for a variety of interface functions in the microprocessor. PPI 8255 has 24 I / O pins which are divided into three 8-bit ports. These ports are port A (PA0-PA7), port B (PB0-PB7) and port C (PC0-PC7). As a path for transferring data to and from PPI 8255 an 8 bit data bus channel (D0-D7) is provided. The data bus from this PPI can be connected directly to the data bus from a microcomputer.
IGBTs for driving PDPs that respond to the high-speed switching characteristics and low loss characteristics demands that accompany reduced power consumption and higher video quality. We have achieved the ideal IGBTs for driving PDPs by taking full advantage of the IGBT characteristic of low power loss in the high current region compared to power MOSFETs.
Points on Appeal (Features)
1. Can control high currents. 2. Heat generation during circuit operation is minimized through high-speed switching and low VCE(sat) characteristics
