__ __ Y1 -| 1 14 |- VCC A1 -| 2 13 |- B1 A2 -| 3 12 |- C1 B2 -| 4 11 |- D1 Y2 -| 5 10 |- GND D2 -| 6 9 |- C2 C2 -| 7 8 |- B2 ----------

Functional Features

  • Dual 4-input AND gate: Accepts four input signals (A1, A2, B1, B2) and produces a single output signal (Y1, Y2) based on the logical AND operation.
  • Low-voltage operation: Can be powered by a supply voltage as low as 1.65V, making it suitable for low-power applications.
  • Fast propagation delay: The typical propagation delay time of 6.3ns ensures quick response in digital circuits.
  • Low quiescent current: Consumes only 2μA of current when not actively switching, reducing power consumption.

Advantages and Disadvantages

Advantages: - Low-voltage operation allows compatibility with a wide range of systems. - Fast propagation delay enables high-speed data processing. - Low quiescent current minimizes power consumption.

Disadvantages: - Limited to AND gate functionality, may not be suitable for all logic operations. - TSSOP package may require careful handling during assembly.
