74HC595, DIP 16 package, +2x100nF +100K +220K

The 74hc595 is a 8-bit shift register with output latches. It is designed to be used as a 8-bit serial to parallel port expander.

The 74hc595 can add additional digital output lines to any Microcontroller. It uses 3 output lines on the Microcontroller and provides 8 (one 74HC595) or 16 (two 74HC595) digital outputs.

See article AVR I/O-web server with additional output pins via a 74hc595 port expander for a description on how to use the 74hc595.

Operating voltage range: 2.0V to 6.0V
Maximum DC output current per pin: 35mA
Package: 300mil 16 pin DIP
Maximum clock freq.: 4.8MHz at 2V, 28MHz at 6V

Two capacitors (2 x 100nF) and two resistors (100K + 220K) are included together with the 74hc595. Those components can be used to keep the output lines of the 74hc595 at a defined state during power on. See the above article for a circuit diagram.
