PCA9674 PCA9674A Remote 8-bit

The PCA9674/74A is a drop-in upgrade for the PCF8574/74A providing higher Fast-modePlus I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWMdimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devicescan be on the bus without the need for bus buffers, highe ...

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 ...

Emulating a synchronous serial

The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...
