The 7405 Hex Inverter Open Collector IC is a TTL (Transistor-Transistor Logic) integrated circuit that contains six independent NOT gates (inverters), each featuring open-collector outputs. It is part of the popular 74xx logic family, designed for digital logic applications. The open-collector configuration allows the outputs to sink current but not source it, making it ideal for driving LEDs, relays, or interfacing with higher voltage levels through external pull-up resistors.
Packaged in a DIP (Dual Inline Package) format, the 7405 IC is easy to handle, solder, or insert into a breadboard or IC socket, making it highly suitable for educational, prototyping, and embedded system projects. It operates using standard 5V TTL logic levels, making it compatible with microcontrollers and digital circuits.
Features:
- Contains six independent inverter gates in one IC package.
- Open-collector outputs suitable for wired-AND and level-shifting applications.
- Compatible with all standard TTL and CMOS logic families.
- Wide operating voltage range for flexible circuit design.
- High noise immunity and stable logic operation.
- Low power consumption and fast switching response.
- Easy to mount in DIP-14 through-hole packages for breadboards and PCBs.
