The MOC3020 Series consists of gallium arsenide infrared emitting diodes, optically coupled to a silicon bilateral switch.Recommended for 115/240 Vac(rms)
This powerful (200 nanosecond instruction execution) yet easy-to-program CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into an 40- or 44-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
The CD4017 is a popular CMOS integrated circuit (IC) that functions as a decade counter/divider, counting from 0 to 9 with ten individual decoded outputs, ideal for sequential projects like LED chasers or frequency dividers. It advances its output state with each clock pulse, resetting after ten counts, and features wide voltage tolerance (3V-15V) and good noise immunity, making it versatile for various digital applications.
