Dual J-K negative edge-triggered flip-flop
The 74ALS11 is a 14 pin dual 4-input AND gate logic device manufactured by Texas Instruments and National Semiconductor. It is a member of the 74ALS logic family, which is a low-power Schottky-clamped CMOS logic family. The 74ALS11 has two 4-input AND gates, each with four independent inputs and one common output. The inputs are active low, meaning that a logic low (0) at the input will result in a logic high (1) at the output. The device has a propagation delay of 8.0ns and a maximum power dissipation of 500mW. The 74ALS11 is used in applications such as logic level conversion, bus arbitration, and multiplexing. It is also used in digital logic circuits, computer systems, and communication systems. (For reference only)
