The 74FCT821BSC is an integrated circuit (IC) component that belongs to the 74FCT series of enhanced performance CMOS logic. It is specifically designed to act as an 11-bit buffer with 3-State outputs, capable of driving high-capacitive loads while maintaining a low-power consumption. The IC is manufactured by various semiconductor companies and is available in a small-outline integrated circuit (SOIC) package.
Here are some key features and characteristics of the 74FCT821BSC:
1. Inputs and Outputs: The IC has 11 input pins, labeled as A0 to A10, and 11 output pins, labeled as Y0 to Y10. These inputs and outputs are TTL-compatible and can interface easily with other logic ICs.
2. 3-State Outputs: Each output pin of the IC can be independently tri-stated, allowing multiple outputs to share the same bus lines without any contention. This feature offers flexibility in designing bus-oriented systems.
3. Output Drive: The IC is designed to have high output drive capabilities, which ensures efficient driving of capacitive loads. It can comfortably drive heavily loaded circuit boards or long traces without any signal degradation.
4. Schmitt Trigger Inputs: The input pins are equipped with Schmitt trigger circuitry. This allows the IC to handle noisy or slowly transitioning input signals effectively. The Schmitt trigger helps eliminate issues caused by noise, such as false triggering or glitches
