Description
Logic gates are a great way to perform basic logic functions in a circuit without involving a microcontroller or programming. There are several different types of logic gate available making fairly complicated logic possible.
This basic OR gate has two inputs and one output per channel and 4 total channels. The chip’s internal circuitry looks at both of the input lines and makes a decision whether or not the output should be switched on (HIGH) or turned off (LOW).
OR Gate logic:
• If both inputs are LOW, the output will be LOW
• If one of the inputs are HIGH, and the other is LOW, the output will be HIGH
• If both inputs are HIGH, the output will be HIGH
Features
- 2 inputs and 1 output per channel
- Voltage: 2V – 6V
- 4 channels
- Current Output: 5.2mA
