Frequently Asked Questions
What logic function does the SN74LV21APW-P perform?
The SN74LV21APW-P contains two independent 4-input AND gates. Each gate produces a high output only when all four of its inputs are high, making it useful for multi-condition enable logic, address decoding, and combinational logic reduction in digital circuit design.
What supply voltage range does the SN74LV21APW-P support?
The SN74LV21APW-P operates over a supply voltage range of 1.65V to 5.5V, providing compatibility with 1.8V, 2.5V, 3.3V, and 5V logic systems. This wide range makes it suitable for use across a broad range of embedded, industrial, and consumer electronics platforms.
What package does the SN74LV21APW-P use?
The SN74LV21APW-P is available in a 14-pin TSSOP (Thin Shrink Small Outline Package). This compact surface-mount package is compatible with standard reflow soldering processes and is well-suited for high-density PCB designs in industrial and portable electronics applications.
What are typical applications for the SN74LV21APW-P?
Typical applications include address decoding, interrupt masking, clock enable gating, and multi-input combinational logic circuits. The dual 4-input AND functionality makes it ideal wherever multiple simultaneous conditions must all be true before an action is triggered in digital control systems.
Are there pin-compatible alternatives to the SN74LV21APW-P?
Pin-compatible alternatives include the SN74LV21A in SOIC or other packages, and the SN74AHC21 for higher-speed applications. When substituting, verify supply voltage range, propagation delay, and drive current specifications to ensure the replacement meets your circuit's timing and loading requirements.
