74LS21 Dual 4-input AND Gate SMD IC
The 74LS21 Dual 4-Input AND Gate SMD IC is a digital logic device containing two independent 4-input AND gates. Each gate within this IC outputs a high signal only when all four inputs are high, allowing it to perform complex logical operations in digital circuits. This IC is particularly useful in applications requiring multiple conditions to be met simultaneously before triggering an action, making it a valuable component in control systems, data processing, and timing circuits. The 74LS21 operates with Transistor-Transistor Logic (TTL) levels and is part of the 74LS logic family, known for its low power consumption and faster switching speeds, providing reliable performance across various applications. Each gate in the IC can be configured separately, offering flexibility in handling different logical conditions. The dual nature of the IC allows for two distinct 4-input AND operations within a single package, saving board space and reducing the need for additional components in complex designs.
Features:-
- High-Speed Operation
