Bus switch for signal isolation and hot-swap
The 74CBTLV3125QG is a 4-channel bus switch from the 74CBTLV series, configured as 1 x 1:1 per channel. Each switch acts as a low-ohmic pass gate — when enabled, the signal passes with minimal propagation delay; when disabled, the output is high-impedance, isolating the bus. This makes it a direct fit for hot-swap bus isolation, I²C/SMBus buffering, or multiplexing digital signals where you need to disconnect a node without affecting the rest of the bus.
Temperature grade and environment
Rated for -40°C to 85°C. The surface-mount QSOP package is suitable for reflow soldering.
Lifecycle and sourcing
The 74CBTLV series is a standard logic family, so supply through independent distribution is consistent.
