The SN74CBTLV3126PWRG4 is a low-voltage quadruple FET bus switch designed for efficient signal routing in various applications, including datacenter computing and wired networking. It features a standard 126-type pinout and provides a 5-ohm switch connection between two ports, enabling rail-to-rail switching on data I/O ports. Each switch can be independently controlled, with an output-enable (OE) input that disables the switch when low. The device supports partial-power-down mode operation through its I_{off} feature, preventing backflow of damaging current when powered down. It is available in multiple package options, including TSSOP, and operates within a temperature range of -40 to 85 degrees Celsius. The latch-up performance exceeds 100 mA per JESD 78, Class II, making it suitable for robust applications.
