The 74HC21D,652 is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) integrated circuit (IC) component. It belongs to the 74HC family of logic gates and is specifically a dual 4-input AND gate. Here is an overview of its key features:
1. High-speed operation: The 74HC21D,652 is designed to work at high-speeds, making it suitable for applications that require fast signal processing.
2. CMOS technology: It utilizes CMOS technology, which provides low power consumption, high noise immunity, and a wide operating voltage range.
3. Dual 4-input AND gate: The IC contains two separate 4-input AND gates in a single package. Each gate can accept four different input signals and produces a logic HIGH output only if all the inputs are logical HIGH.
4. Schmitt-trigger inputs: The inputs of the 74HC21D,652 are equipped with Schmitt-trigger action, allowing for easy interfacing with digital circuits operating at different voltage levels. This feature enhances the device's noise immunity and protects against input signal fluctuations.
5. Wide voltage compatibility: It operates over a broad range of power supply voltages, typically ranging from 2V to 6V. This flexibility in voltage compatibility makes it compatible with a wide array of electronic systems
