单片机编程 PCA9546A 4 channel I2C bus swi
The PCA9546A is a quad bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.
单片机编程 1A SIMPLE STEP-DOWN SWITCHING
The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...
单片机编程 3-V TO 5.5-V MULTICHANNEL RS-2
The MAX3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge)protection on serial-port connection pins. The device meets the requirements of TIA/EIA-23 ...
