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.
