Description
7437 Quad 2 Input
NAND Buffer
IC DIP-14
The 7437 Quad 2 Input NAND Buffer IC DIP-14 is a TTL logic device containing four independent 2-input NAND buffer gates designed for use in high-speed digital systems. Each gate provides buffered outputs for increased drive capability, making the device suitable for driving relatively low-impedance loads and interfacing between logic stages where higher fan-out is required. The IC is implemented using low-power Schottky technology, offering a balance of low power consumption and fast switching characteristics in comparison with standard TTL families.
Features:
Contains four independent 2-input NAND buffer gates.
Buffered outputs for increased drive capability.
High sink current of up to 24mA in low output state.
Compatible with TTL logic levels.
Low propagation delay for efficient signal processing.
