The SN7405DR is an Integrated Circuit (IC) component used in electrical circuits to perform various logic functions. It belongs to the 7400 series of TTL (Transistor-Transistor Logic) ICs, which are widely used in digital circuits.
The SN7405DR is a hex inverter with open drain outputs. It consists of six individual inverters, which means it can invert the logical input level and provide the inverted output. The open drain outputs feature allows the IC to be connected to other devices or circuits in a wired-OR configuration.
Some of the key features of the SN7405DR IC include:
1. Hex Inverter: The SN7405DR has six inverters, allowing it to handle six different input signals simultaneously. Each inverter has one input and one output.
2. Open Drain Outputs: The outputs of the inverters in SN7405DR are designed as open drain, which means they can be connected to external devices or circuits and can pull the output voltage to a low logic level (ground) when activated.
3. TTL Compatibility: The SN7405DR operates on TTL logic levels, which are compatible with other TTL ICs. It ensures seamless integration with other digital logic components.
4. Wide Operating Voltage: The IC has a wide operating voltage range, typically from 2V to 6V. This allows it to be used in a variety of applications with different voltage requirements
