SN74ABT2244ADBR is an integrated 4-bit bus transceiver designed to provide two independent transceivers or a bi-directional buffer between a 4-bit data bus and two bidirectional busses in a high speed CMOS device. SN74ABT2244ADBR supports a wide range of control functions and flexible data transmission style, making it ideal for general data transmission and buffering applications. It is optimized to provide low-capacitance data (L-C-D) transmission over short distances with minimal power consumption. SN74ABT2244ADBR is a member of Texas Instruments’ broad range of low-power, high-speed, non-volatile memory solutions.

Application Field for SN74ABT2244ADBR

SN74ABT2244ADBR is an ideal component for applications related to short distance data transmission, as it has high speed and low capacitance data transmission capabilities. Moreover, its wide range of control functions, allows for flexible data buffering and transmission, making it suitable for applications such as in communication buses, synchronization of multiple data sources, tiling of 4-bit data sources, and so on.

The low-power and low-capacitance data transmission capabilities of SN74ABT2244ADBR also make it ideal for data storage and memory applications. Because this IC operates under stringent back-bias conditions, it can provide high data storage densities in smaller form factors than other ICs. In addition, this type of transceiver is ideal for use in systems that require low latency due to its low capacitance design.

Working Principle of SN74ABT2244ADBR

SN74ABT2244ADBR is based on Texas Instruments’ Ultra-Low Power (ULP) CMOS logic technology. This device consists of seven active pull-up and pull-down transistors, four of which are for L-C-D data transmission and three of which are for control signals. It also has three control inputs which provide the capability to control data flow in either direction. The data buses are buffered in both directions, so that the buffered data can be transmitted over short distances with minimal power consumption.

The SN74ABT2244ADBR transceiver contains two output drivers, which are used to rapidly transmit the buffered data over the four-bit data bus. The low capacitance design of the driver circuit ensures faster data transmission rates. The control inputs are used to select between four operation modes, which can be configured by the user: Data transmission modes, data bus control modes, data storage modes, and mask modes.

The Data transmission modes of SN74ABT2244ADBR are used to transfer the buffered data between the four-bit data bus and the two bidirectional busses. The Data bus control mode can be used to control the flow of data from the four-bit bus to the two bidirectional busses. The Data storage mode allows the transceiver to store the data from the four-bit bus and then forward it to both the bidirectional busses. Finally, the Mask mode can be used to mask the data in the four-bit bus, so that only selected data is transferred.

Conclusion

SN74ABT2244ADBR is a versatile four-bit bus transceiver designed by Texas Instruments to provide reliable and high-speed data transmission. It is ideal for use in applications related to data transmission, buffering, synchronization, and memory storage. The device has eight control inputs, which can be used to configure the device’s operation modes. Additionally, this transistor’s low capacitance design makes it suitable for short distance communication applications.
