Introduction
The 74ACTQ244SJX is a quad bus transceiver from the 74ACT logic family that consists of four non-inverting buffers and drivers. It is used for logic conversion between TTL and CMOS logic families, and is connected to an output enable input (OE) that is used enable or disable the output drivers. This transceiver enables data communication between two logic families and is commonly used as bus transceiver, bidirectional buffer, three state buffer, and different types of interface circuit.
Application Field of 74ACTQ244SJX
The 74ACTQ244SJX is a quad bus transceiver design specifically for logic conversion between TTL and CMOS logic families. It is a high performance bus transceiver and is suitable for various applications such as automotive, telecommunications, industrial, commercial, and consumer electronics. It can be used as an interface between digital and asynchronous systems. The OE input in this transceiver allows for power saving, as the output drivers can be disabled when the output is not required.
The 74ACTQ244SJX is used for improved system performance, acting as a bridge between TTL logic and CMOS logic. It provides level shifting from one logic family to another and helps protect the output from noise and other interferences across families. It is also suitable for various data communication applications such as parallel-to-serial and serial-to-parallel data conversion. This transceiver is also used in data buses, address select/access memories and memories, ADCs/DACs, and other systems.
Working Principle of 74ACTQ244SJX
The 74ACTQ244SJX quad bus transceiver is a four-input, four-output logic device and consists of four inverting buffers and drivers. It is designed to transfer data between the CMOS and TTL logic levels. It has an active-high output enable (OE) input for disabling and enabling the output buffers of the device. When OE is enabled, the outputs of the transceiver are enabled, and the transceiver transfers data from the A inputs to the Y outputs and vice versa.
There is an internal pull-up resistor in this transceiver that is used to pull the output enable (OE) pin to the high-level state. When the OE is enabled, the outputs of the transceiver are enabled, and the transceiver transfers data from the A inputs to the Y outputs and vice versa. The OE is disabled whenever there is a high-level logic on the OE pin. In this case, the outputs of the transceiver are disabled and the device is in a high-impedance state.
The 74ACTQ244SJX can be used as a transceiver, a bidirectional buffer, a three-state buffer, or an interface circuit. It provides level shifting from one logic family to another and helps protect the output from noise and other interferences across families. Additionally, it provides protection from excessive currents resulting from one logic family being connected to another.
Conclusion
The 74ACTQ244SJX is a quad bus transceiver design specifically for logic conversion between TTL and CMOS logic families. It is suitable for various applications such as automotive, telecommunications, industrial, commercial, and consumer electronics and is used for improved system performance, acting as a bridge between TTL logic and CMOS logic. The OE input in this transceiver allows for power saving, as the output drivers can be disabled when the output is not required. Additionally, it provides protection from excessive currents resulting from one logic family being connected to another.
