8-Bit Parallel-In/Serial-Out Shift Register - 74HC165N

The SN74HC165N is a neat little IC that will take an input of up to 8 parallel lines and produce a single, serial output. You can even daisychain 2+ together to add even more parallel lines. It's a great way to increase the number of inputs on a microcontroller.

This chip works with a voltage supply anywhere in the range of 2-6VDC, and at clock frequencies of up to 29MHz (@6VDC).

Comes in a 16-pin DIP package.

Features:

• Wide Operating Voltage Range of 2 V to 6 V
• Parallel-to-Serial Data Conversion

• Low Power Consumption, 80-μA Max ICC
• ±4mA Output Drive at 5 V
• Low Input Current of 1 μA Max
• Complementary Outputs
• Direct Overriding Load (Data) Inputs
• Gated Clock Inputs
