ONSEMI Quad Analogue Comparator, 1.3µs, SOIC-14

The ONSEMI LM339DR2G is a high-performance, single-supply quad analogue comparator engineered for precision level detection, low-level sensing, and memory applications. This versatile IC operates from a broad voltage range of 3V to 36V, making it suitable for a wide array of power management and industrial control systems.

A key advantage of this device is its exceptionally low input bias current, typically just 25nA, coupled with a low input offset current of ±5nA. This ensures high accuracy in sensing applications. The comparator features an input common-mode voltage range that extends down to ground (GND), and its outputs are both TTL and CMOS compatible, offering excellent flexibility for interfacing with different logic families.

For enhanced reliability in demanding environments, the inputs include integrated ESD protection clamps. These safeguards increase the device's robustness against electrostatic discharge without compromising its operational performance. The output type is open collector, providing the user with greater design flexibility for wired-OR configurations and easy level shifting.
