The SE521F from NXP Semiconductors is a high-speed dual-differential comparator designed for applications requiring fast response times. It boasts a maximum guaranteed propagation delay of 12ns and a low maximum input bias current of 20μA. The device operates from standard supply voltages and features TTL-compatible strobes and outputs, making it suitable for integration into various digital systems.
This comparator is available in multiple package types, including 14-pin Plastic Dual In-Line Package (DIP), 14-pin SO Package, and 14-pin Ceramic Dual In-Line Package (CERDIP). The operating temperature range for the NE521 variant is 0 to +70°C, while the SE521 variant operates from -55°C to +125°C, offering flexibility for different environmental conditions.
Key electrical characteristics include a large common-mode input voltage range and specific input voltage levels for low and high states. The device also specifies absolute maximum ratings for supply voltage, differential input voltage, and power dissipation, which vary by package type. These specifications make the SE521F a robust choice for demanding applications.
