The HEF4043BP is a quad D-type latches IC (integrated circuit) component produced by Nexperia. It belongs to the HEF4043 family of CMOS (complementary metal-oxide-semiconductor) integrated circuits. The IC is primarily used for storing or latching data in digital systems.
This IC has four independent latches, each comprising a D-type flip-flop circuit. It operates with a wide supply voltage range, typically from 3V to 15V, which makes it suitable for various digital logic applications.
Key features of the HEF4043BP include:
1. Quad Latch Functionality: The IC contains four individual D-type latches, which allows for the storage of four separate data inputs independently. This makes it convenient for multiplexing or storing multiple data streams.
2. High Noise Immunity: The HEF4043BP incorporates advanced CMOS technology, ensuring high noise immunity. This helps in reducing errors or signal distortions caused by external noise sources.
3. Standardized Pinouts: The IC follows standard pinouts for easier integration into different circuit designs. The pin configuration includes separate input and output pins for each latch, along with power supply and ground pins.
4. Schmitt-trigger Inputs: The IC features Schmitt-trigger inputs on all of its latch enable inputs. The Schmitt-trigger characteristic enhances the noise immunity and permits hysteresis, allowing the IC to tolerate slow or degraded input signals more effectively
