The CD4043BD is an integrated circuit (IC) component that belongs to the CMOS (complementary metal-oxide-semiconductor) family of logic chips. It is a quad cross-coupled CMOS NAND gate latch with 3-state outputs. This IC is primarily used in digital electronics for various applications such as data latching, address decoding, and various control functions.
Key Features:
1. Quad Cross-Coupled Latches: The CD4043BD consists of four individual latch circuits that can store a single bit of information each. These latches are interlinked together in a cross-coupled configuration, offering stable storage and output.
2. CMOS Technology: Built using CMOS technology, this IC component provides low power consumption, high noise immunity, and wide supply voltage range. These characteristics make it suitable for battery-powered devices and applications where power efficiency is crucial.
3. 3-State Outputs: The CD4043BD features 3-state (high-impedance) outputs, allowing multiple devices to share a common bus. This feature facilitates bus contention and eliminates the need for additional external components to control the bus access.
4. Schmitt-Trigger Inputs: The inputs of this IC are equipped with Schmitt-trigger action. It ensures robust and reliable signal transfer by eliminating problems associated with slow or noisy input transition.
5. Wide Operating Voltage: The CD4043BD can operate within a wide voltage range, typically from 3V to 15V
