SN74ABT863NTG4

The SN74ABT863NTG4 from Texas Instruments is a 10-bit transceiver buffer with a 2.5V–3.6V operating voltage range. It has 8-bit transmit/receive register with independent chip selects and a single control line. With this feature, it is well suited for high speed, low power logic interfacing applications.

Application Field

The SN74ABT863NTG4 is designed for applications where high-speed transmission of data is a must. It is commonly used in industries such as automotive, industrial, communications, and consumer electronics. It is commonly found in video-game consoles, mobile phones, digital cameras, flat-panel displays, digital signal processing equipment, and optical drives.

Working Principle

The SN74ABT863NTG4 is a logic-level translator solution for data buses which require signal conversion between different voltage levels. It is an 8-bit dual-data rate transceiver operated in an asynchronous mode. It consists of two independent 8-bit transmit/receive registers with independent chip selects that each may be independently enabled. The transmitter and receiver each have their own complementary 3-state output that is driven to the appropriate output voltage setting. This allows the data lines to provide both the high logic level voltage and the low logic level voltage (VTT and VTTX respectively) to the target device. When enabled, the receiver is able to accept data which is formatted and sent on the respective bus.The SN74ABT863NTG4 also features a single control line that allows the user to control the overall operation of the device. The control line can be used to enable the device, disable the device, or toggle the output levels of the device. It also contains a pair of bidirectional control carriages which allow for high speed data transfers between chips of varying logic voltages.

Conclusion

The SN74ABT863NTG4 is a high-speed transceiver buffer that is suitable for applications where reliable performance, low power consumption, and high speed are a must. Its 8-bit transmit/receive register with independent chip selects and a single control line, and its bidirectional control carriages make it a suitable choice for high speed logic interfacing applications.
