DM74ALS244ASJX is a member of the 4000B CMOS Logic complimentary metal-oxide-semiconductors series produced by Fairchild Semiconductor. It is a 3-state non-inverting buffer and bus transceiver device. The device is fabricated using high-performance complementary metal-oxide semiconductor processes that are specifically designed for high speed logic applications.The device has an 8-bit data output port and an 8-bit data input port. It also has an active-LOW enable input (E) that has active-LOW inputs that allow the device to be connected to either a low voltage or high voltage bus. The output enable (OE) input can also be used to enable or disable the device\'s outputs.The DM74ALS244ASJX is used in various applications such as bus interface, bus transceiver and bus buffer. It is also used in microprocessor based systems for memory expansion, in address decoding logic and memory mapping logic. The device is commonly used in address buffering and data transfer applications in high-speed data processing systems.The device provides fast data transfer and excellent noise rejection. Its output levels are compatible with TTL and CMOS levels. The device also provides output-to-input logic level conversion. This allows for fast data transfer rates of up to 500 MHz.The DM74ALS244ASJX device works on the principle of buffering and storing data. When the enable input is activated, the device takes data from the input port and stores it in a buffer register. The stored data is then sent to the output port. Output signals are only enabled when the enable input is activated.The active-LOW input signals on the enable input (E) and output enable (OE) pins are used to control the state of the device. When both of these inputs are low, the outputs are disabled. When the E input is low, the device is held in the disabled state even if the OE input is high. When the E input is high and the OE input is low, the device is enabled.The DM74ALS244ASJX is used in a wide range of applications. Its application field includes bus interface, bus transceiver and bus buffer. It is also used in microprocessor based systems for memory expansion, in address decoding logic and memory mapping logic. The device provides fast data transfer rates of up to 500 MHz and low noise levels. It is also compatible with TTL and CMOS logic levels.
