The HEF40244BT,653 is a logic circuit that can be categorized under Logic: Buffers, Drivers, Receivers, Transceivers. It is a 5-stage shift register with send/receive capabilities and open drain outputs. It is designed to provide an easy interface between digital systems and other devices such as microprocessors, memories, and bus configurations.

The device is characterized by a power supply operating range of 1.5 V to 3.6 V, and a maximum supply voltage of 4 V. The device is able to provide good support for communication between digital systems and other devices over a distance of up to 10 meters. It is constructed with a combination of CMOS and HC logic, and has an output voltage swing of up to 2.4 V.

The HEF40244BT,653 incorporates two main views: a send and receive view. In the send view, data is sent out to the I/O pins while in the receive view, data is received from the I/O pins. By using the output register and input register, the device can switch between send and receive views according to the signals present on its receive/transmit pin and receive line. The device is powered by a single PC board and requires no external components.

The HEF40244BT,653 draws its working power from the supply voltage, and works in different voltage levels. When the device is in a send mode, the output from the register is given to the I/O pins. The device is controlled by two independent clocks, a transfer clock and a shift clock. The transfer clock is used for the shifting of data. Whenever the transfer clock gets a positive edge, the data is shifted in the register. The shift clock is used for selecting which registers are in use, and this clock also controls the direction of data flow.

When the device is in a receive mode, data is received from the I/O pins and shifted through the registers. When the device is in idle mode, it does not send data or receive data and the output is high-impedance. In this mode, the receive/transmit pin and receive line monitors the pins and then switches the logic state accordingly.

The HEF40244BT,653 has a wide range of application fields including digital communication systems such as USB, RS-232, ISA bus, as well as in process control systems, robotics and machine vision applications. The device is extremely small and very cost efficient and is a great addition to digital systems. It is capable of communication over long distances, making it a reliable logic component.
