Texas Instruments High-Performance Analog Signal Switches, Multiplexers, Decoders SN74CBT3384CDW

The SN74CBT3384C is a 10-bit FET bus switch designed for high-speed applications, featuring bidirectional data flow and low ON-state resistance, typically 3 ,Ѷ. It includes active undershoot protection for both A and B ports, safeguarding against undershoot events up to -2 V. The device operates within a voltage range of 4 V to 5.5 V and supports various signaling levels from 0 to 5 V, making it versatile for different applications. This bus switch is organized as two 5-bit switches with separate output-enable inputs, allowing for flexible configurations. When enabled, it connects the A and B ports, facilitating data transfer, while disabling the switch places it in a high-impedance state. The device also features low input/output capacitance (5 pF typical), which minimizes loading and signal distortion, and low power consumption, with a maximum ICC of 3 ¬µA. The SN74CBT3384C is suitable for both digital and analog applications, including PCI interfaces and memory interleaving. It is fully specified for partial-power-down operation, ensuring no backflow current occurs when powered down. The device's latch-up performance exceeds 100 mA, and it has been tested for ESD performance per industry standards.
