。Application Field and Working Principle of MC74HC245ADT
The MC74HC245ADT is a logic device from the 74HC series logic family. It belongs to the Logic Buffers, Drivers, Receivers, Transceivers (BDTR) category. Operating at a supply voltage between 2 and 6 Volts, it is applied in interfacing circuitry such as microprocessor system, signal repeater or signal buffer, where high-speed data transmission, voltage level conversion and/or signal buffering between two nodes are required.
Overview
The MC74HC245ADT is a high-speed octal transceiver gate with 3-state outputs and 3-state inputs. It is designed to accommodate bus-oriented system applications where the devices connect with the high-speed buses and low-power I/O. The I/O interface capability is suitable to allow direct data transfers and data buffering between two circuits with different voltage levels. Moreover, it has two and four control pins (output enable, output control and active low enable, respectively) for tri-state output and low power supply management.
Advantages
The MC74HC245ADT has several advantages. First, its octal transceiver gate is ideal for data communication and buffering. Second, its capability for direct data transfers and data buffering between two circuits with different voltage levels makes it suitable for interfacing circuitry applications like microprocessor systems, signal repeaters and signal buffers. Third, the two and four control pins (output enable, output control and active low enable, respectively) allow it to manage tri-state outputs and low power supply. Moreover, a variety of options is available to extend its features such as operating temperature, package, etc.
Function
The MC74HC245ADT functions as an octal transceiver gate with 3-state outputs and 3-state inputs, establishing a communication link between two circuits. The communication is made through data linelines, which are buffered and can be used as a signal source. The device has eight data input/output pins, two and four control pins (output enable and output control and active low enable, respectively) and one ground lead to insure proper operation of the device.
Working Principle
The MC74HC245ADT is able to provide direct data transmission and data buffering between two circuits with different voltage levels.This is achieved by the combination of its two and four control pins (output enable, output control and active low enable, respectively) of the gate. The output enable pin is connected to the source side. When it is set to a high logic level, the gate is enabled and the output is enabled. The output control pin is connected to the sink side and when it is set to a low logic level, the gate is enabled and the output is enabled. The active low enable pin is connected to both sides and when it is set to a low logic level, the output is disabled. The device is able to provide data buffering by connecting the data output pins of the source device to the data input pins of the sink device through the gate.
Conclusion
In conclusion, the MC74HC245ADT is a logic device from the 74HC series logic family. It belongs to the Logic Buffers, Drivers, Receivers, Transceivers (BDTR) category and is suitable for direct data transmission and data buffering between two circuits with different voltage levels. This makes it ideal for interfacing circuitry applications like microprocessor systems, signal repeaters and signal buffers. It is designed with three-state outputs and three-state inputs, two and four control pins (output enable, output control, active low enable and ground lead) to provide direct data transmission and data buffering.
