MC74AC244DTR2G

The MC74AC244DTR2G is a logic device which belongs to the Buffers, Drivers, Receivers, Transceivers category of logic devices. It is a low-cost, low-power, bidirectional bus transceiver. It is designed to operate as a level translator with TTL or CMOS inputs and outputs. This device has high-impedance input/output lines and allows bi-directional data transmission over a single bus. It has two active-low enable inputs which can be used to individually enable data flow in either direction. The MC74AC244DTR2G also features open-collector outputs which provide increased drive capability for improved noise immunity.

The MC74AC244DTR2G is used in a variety of applications such as logic level translation, bus arbitration and data multiplexing. It is often used as a level translator in interfaces between 8-bit and 16-bit systems. It is also used as an expansion port for microcontroller systems. The primary applications for this device are in the fields of telecommunications, automotive, network, memory and processor designs.

The working principle of the MC74AC244DTR2G is simple and straightforward. It consists of two independent bidirectional ports, each with three-state outputs and open-collector outputs. Each port has an active-low enable input which is used to control data flow in either direction. When the enable input is active, the output lines are driven to the logic levels specified by the data inputs. When the enable input is inactive, the output lines are placed in a high-impedance state to prevent current flow. By controlling the enable input, data can be transferred bidirectionally through the device.

The MC74AC244DTR2G is a versatile device which provides a highly reliable solution for logic level translation. It is also suitable for use in high-speed applications as it has a maximum data rate of 100MHz. The device is offered in an SOIC package and is compliant with the RoHS directive. The device is rated for operation over the full temperature range of -40°C to +85°C.
