What is IC 74LS244 called?
The IC 74LS244 is a line driver and buffer integrated circuit. It features eight non-inverting buffers with a high-speed output, designed for driving large capacitive loads while maintaining signal integrity. It is commonly used in digital circuits for signal conditioning and interfacing purposes. The "LS" in its name indicates that it is part of the Low Power Schottky family, which offers faster operation with lower power consumption compared to standard TTL devices.
How can communication be achieved between computer processor and adapter card?
In these days it becomes possible for the designers to connect the personal computers with some outside apparatus by means of integrating suitable adapters which can be fixed in the expansion slot. It is one of the adequate methods know to be used in connection and communication. Assembly language which is needed to achieve the communication between the card and the processor inside computer using 74LS244 chips and line drivers with three states output to provide a unidirectional buffering for sixteen computer lines. We can achieve communication between computer processor and adapter card by using assembly language instructions. We attached the hardware to the computer and write the desire output containing programs by using given BIOS services in assembly language. These are assembly instructions in the given program. MOV, use to move data from one register to another OUT, for the output DEC, decrement data INC, increment data JUZ, different types of jumps etc JN
