SN74LV595APWR IC_AD215AY Introduction

However, in view of the sluggish semiconductor market in 2019 and the unsatisfactory revenue situation, TI's plan to invest in the construction of a 300mm wafer fab in Richardson is not as smooth as originally expected, and it may be delayed for two years to complete. In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of $3.1 billion.

Combining EtherCAT, Ethernet and CAN FD: In terms of galvanically isolated architecture, the new microcontrollers feature a fast serial interface with 8 receive channels, enabling chip-to-chip communication at speeds up to 200 Mbps with fewer pins. .

The resonator used by the ladder type (SAW also mentioned at the end) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages. .

The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp). The working principle is as shown below.
