SN74CBT16210CDGGR: High-Bandwidth Bus Switch from Texas Instruments

The SN74CBT16210CDGGR is a 20-bit FET bus switch designed by Texas Instruments to provide high-speed switching on data paths. This integrated circuit is a part of the CBT (Crossbar Switch Technology) family, which is known for its low power consumption and high-speed operation.

Constructed with an advanced BiCMOS technology, the SN74CBT16210CDGGR is capable of achieving a significant reduction in power consumption without sacrificing speed, making it an ideal choice for power-sensitive applications. The device features a 5-ohm bidirectional switch that enables the connection or isolation of two ports by the control input signal.

The bus switch is organized as two 10-bit buses with individual output-enable (OE) inputs. This allows for greater flexibility in application, as each 10-bit section can be controlled independently, enabling or disabling the connection between the input and output ports. This feature is particularly useful in applications that require data multiplexing, signal gating, or bus isolation.

Key specifications of the SN74CBT16210CDGGR include:

• Operating Voltage: The device supports a wide range of operating voltages from 4.5 V to 5.5 V, making it compatible with standard TTL (Transistor-Transistor Logic) levels.
• Low On-State Resistance: The switch's on-state resistance is typically 5 ohms, providing efficient signal transmission with minimal signal distortion.
• Quick Switching: The switch is designed for high-speed operation, with a typical switching time of 0.25 ns, ensuring minimal delay in signal propagation.
• Low Power Consumption: It features a low quiescent power consumption of 10 µA max, which is ideal for battery-powered and portable devices.
• Package: The device comes in a 48-pin TSSOP (Thin Shrink Small Outline Package) that offers a compact footprint suitable for space-constrained applications.

Applications for the SN74CBT16210CDGGR are diverse, ranging from notebook computers, servers, and routers to data communication systems. Its high-bandwidth capability ensures that it can meet the demands of data-intensive environments, while its low power consumption makes it suitable for portable and low-power applications.

Overall, the SN74CBT16210CDGGR from Texas Instruments is a robust, high-performance bus switch that offers designers the flexibility and efficiency needed for modern electronic systems.
