Introduction to 74LVTH16244BDGG,18

The 74LVTH16244BDGG,18, is a high speed low power CMOS octal (eight) latched transceiver manufactured by Texas Instruments. It is a member of the Texas Instruments Logic family and belongs to the Logic - Buffers, Drivers, Receivers, and Transceivers category. The device is used in different applications for switching, multiplexing and transmission of digital signals.

Application Field of 74LVTH16244BDGG,18

The 74LVTH16244BDGG,18 can be used in various applications. It can be used in communication interface systems for multiplexing as it is capable of transmitting high speed data back and forth between two pins. The device is well suited for multiple application purpose likeRS232, RS485, EIA/TIA-232 and 422, Ethernet and other communication buses. It is capable of providing fast switching (up to 30 Mb/sec) and multiplexing. The device is also well suited for low voltage and low power applications.

The device is suitable for applications like data transmission and switching, address encoders/decoders, Data processing/data transfer between two devices, logic-level conversion, 3-state multiplexing, bus or data repeaters and DTMF receivers.

Working Principle of 74LVTH16244BDGG,18

The 74LVTH16244BDGG,18 is an octal transceiver which works in the manner of sending data from the data out (RXD) pin to the data in (TXD) pin. The device is used mainly for data transmission, data switching, address encoders/decoders, logic level conversion and multiplexing. The device operates in the form of 8-bit latched transceiver, the 8-bit bus or latches is named as DIN, DOUT, D0, D1, D2, D3, D4, D5, D6, D7 and SIN. The SIN is used for sending the data in the form of 8-bits from any of the 8-bit pins to the device.

The device is active high, that is, it needs to constantly be supplied with the control signals from the source. The device works on the principle of open collector output principle; when the CPU sends the output-enable signal "OEH" to the device, it enables the data out (RXD) to the data in (TXD) pin, allowing the data to be transmitted through the system.

The device is also equipped with latch enable (LE) and output enable (OE) pins which are used to control the latches and outputs of the device. When the latch enable pin is high the data are latched in the appropriate latches. The output enable pin is used to control the output signals of the device. When the output is enabled the signals are transmitted to the data in (TXD) pin and then it is transmitted through the system.

The device is also equipped with an Enable Strobe pin. This pin is used to strobe the device and thereby allow the device to transmit the data. This pin is an active high pin which must be held high for the device to operate. When it is low then the device is disabled and data is not transmitted. This pin is also used to reset the device.

The device is powered by the power supply (Vdd) and the ground (GND) pins. The device should be connected with an adequate power supply to ensure the proper operation of the device. The device also has a reset pin which can be used to reset all the latches and enables of the device. Thus, this device is capable of transmitting data in a very short amount of time.

Conclusion

The 74LVTH16244BDGG,18 is a member of Texas Instruments Logic family and belongs to the Logic - Buffers, Drivers, Receivers, and Transceivers category. It has various applications for data transmission, data switching, address encoders/decoders, logic level conversion and multiplexing. It is capable of providing high speed transmission of digital data and is well suited for low voltage and low power applications. The device is easy to use and requires very little power to operate. If you are looking for a device that can switch digital data, multiplex signals, or simply provide data transmission, then this is the device to suit your needs.
