Bus-switch selection for mixed-voltage signal routing
The SN74CBTLV3125PWR is a 4-channel bus switch from TI's 74CBTLV series, each channel implementing a 1:1 pass-gate path. It connects or isolates digital signals on a PCB without the propagation delay of a standard logic buffer — the switch's on-state resistance is low enough that the signal sees a near-direct trace. Four independent circuits let you gate four separate signal lines simultaneously, useful for sharing a data bus between peripherals or for hot-swap isolation where the switch disconnects a card before the backplane sees a glitch.
Texas Instruments maintains the standard PCN process; any mask or assembly-site change would be communicated via the TI PCN portal.
