LM360 High Speed Differential Comparator DIP-8

The LM360 High-Speed Differential Comparator is a versatile integrated circuit designed for applications that require rapid signal comparison. Housed in a compact 8-pin DIP (Dual In-line Package), this IC is a workhorse for engineers and hobbyists alike. It delivers exceptional speed and precision, making it suitable for a wide range of tasks, from signal conditioning to high-frequency pulse detection. With a robust design and a wide voltage range, the LM360 effectively converts analog signals into digital outputs, providing clear and reliable results in demanding environments.

Key Features:

• High-Speed Operation: The LM360 can process signals with propagation delays as low as 16 ns, which is crucial for high-frequency circuits.
• Differential Inputs: Use the non-inverting and inverting inputs to accurately compare two different signals, reducing common-mode noise.
• TTL-Compatible Output: This comparator’s output stage is designed to directly interface with TTL (Transistor-Transistor Logic) and DTL (Diode-Transistor Logic) circuits, simplifying integration.
• Wide Operating Voltage: The IC operates reliably across a supply voltage range, providing flexibility for different power supply designs.
• Strobe Capability: An integrated strobe pin allows you to enable or disable the output, giving you precise control over signal flow.
• Dual-Mode Output: The open-collector output can be configured for either active-high or active-low operation by selecting the appropriate output pin.
