Texas Instruments High-Performance Analog Signal Switches, Multiplexers, Decoders SN74CBT3125CD

The SN74CBT3125C is a quadruple FET bus switch designed for high-speed applications, featuring low ON-state resistance (typical ron of 3 ,Ѷ) and minimal propagation delay. It supports bidirectional data flow and is organized as four 1-bit bus switches, each with separate output-enable inputs. The device includes active undershoot protection for the A and B ports, safeguarding against undershoot events up to -2 V, ensuring reliable operation in various conditions. This bus switch operates within a supply voltage range of 4 V to 5.5 V and is compatible with TTL and 5-V/3.3-V CMOS outputs. It has a low power consumption of 3 ¬µA maximum and supports data I/O signaling levels from 0 to 5 V. The SN74CBT3125C is suitable for both digital and analog applications, including USB interfaces and bus isolation, and is fully specified for partial-power-down operation with Ioff support. The device is available in multiple package options, including SOIC and SSOP, and is rated for an operating temperature range of -40¬8C to 85¬8C.
