SN74CBT6800CDBQR 10-Bit FET Bus Switch by Texas Instruments

The SN74CBT6800CDBQR is a high-performance CMOS 10-bit bus switch produced by Texas Instruments that offers a seamless connection between two ports without the propagation delay and ground bounce issues commonly associated with traditional bus exchange methods. Designed to provide the ultimate in low on-state resistance and low-capacitance data path, this switch is ideal for applications that demand minimal signal distortion and maximum signal integrity.

The device features a 10-bit bus switch with a 5-ohm bidirectional switch that connects inputs to outputs. It operates from a 4.5-V to 5.5-V V<sub>CC supply, making it compatible with a wide range of digital systems. The SN74CBT6800CDBQR has been meticulously engineered to minimize crosstalk between buses and is particularly useful in applications where high-speed data transfer is critical.

The switch control is managed by the output-enable (OE) input, which, when asserted low, connects the A port to the B port, thus enabling bidirectional data flow. When OE is high, the connection between the A and B ports is open, and the high-impedance state of the switch prevents data flow, ensuring minimal power consumption and preventing data corruption during power-down modes.

The SN74CBT6800CDBQR comes in a space-saving SSOP (Shrink Small-Outline Package) with 24 pins, designated by the suffix 'DBQR' in its part number. This package is ideal for space-constrained applications without compromising on performance. The device supports plug-and-play installation and is characterized for operation from -40°C to 85°C, making it suitable for industrial temperature ranges.

Whether used in servers, telecommunications, networking equipment, or computing interfaces, the SN74CBT6800CDBQR offers a robust solution for high-speed signal switching. Its fast switching speeds, low power dissipation, and high bandwidth make it an excellent choice for both current and next-generation high-speed data transfer applications.
