The SN74LVC244APWT is an important component in the buffer, driver, receiver, and transceiver, commonly known as LVC, applications. It is an 8-bit bus transceiver, which provides three-state drive outputs, with support for multiple flow control signals from bidirectional buses. The dual-channel, 3-state complementary output buffers are designed to operate from a single 5V supply and are suitable for industrial, commercial and wide temperature range applications. The SN74LVC244APWT also provides support for up to 24mA sink and source current capability.

Working Principle

The SN74LVC244APWT is a single 8-bit bus transceiver designed to provide bidirectional data flow between two independent buses. It is designed to operate with a single 5V supply. The complementary outputs are designed to provide support for up to 24mA sink and source current ability and are suitable for industrial, commercial and wide temperature range applications. The output controls can be controlled individually and can be configured to operate in any of the three possible output states, high impedance, logic low, or logic high.

The SN74LVC244APWT features three flow control signals, which are active low, active high and three-state, commonly known as OEnL, OEnH, and OE. OEnL and OEnH are the enable and disable signals for the low and the high flow control signals, respectively. The OEnL and OEnH logic levels can be controlled independently from the logic levels of the data inputs, allowing for more complex control of the actuator signals. The OE logic level controls the state of the bidirectional data outputs, allowing them to be set to logic high, logic low, or in a high impedance state.

Application Field

The SN74LVC244APWT is ideal for applications that require a bidirectional data transceiver. This type of logic device is commonly used in digital communications, where signals need to be transferred between two separate channels. This device can be used to connect two devices, such as a computer and a printer, or two buses, such as an Ethernet bus and a bus for a control system. This device can also be used for synchronous data transmission, which is commonly used in applications such as audio/video streaming and video conferencing.

The SN74LVC244APWT is also an ideal choice for industrial applications, where data needs to be transferred between two independent buses or devices in a reliable and efficient manner. This device can be used to transmit and receive data in industrial automation systems, as well as for controlling communication and high-speed clock signals. This device can also be used to provide a reliable and secure communication link between multiple sensors, actuators, and digital equipment, as well as to control data flow in a distributed control system.

In addition to being used for digital communication and industrial applications, the SN74LVC244APWT can also be used in wide temperature range applications, such as medical and automotive. This device provides an extended temperature range of −40°C to +85°C and is suitable for applications that require a reliable and low-power transceiver. The SN74LVC244APWT can also be used for power supply monitoring and balancing, data buffering, and signal termination in communications systems.
