Product details

14-VQFN footprint and board integration

The SN74CBTLV3125RGYR comes in a 14-VFQFN Exposed Pad package (3.5x3.5 mm body), supplier device package 14-VQFN. The exposed pad requires a solder paste stencil aperture covering 50-70% of the pad area to avoid voids and ensure consistent solder joint height.

Four independent 1:1 bus switches

This is a 4-bit bus switch with four independent 1:1 circuits, each controlled by a separate output-enable pin. When the OE pin is low, the switch is on and the signal passes through with low on-state resistance; when high, the switch presents a high-impedance state to isolate the bus segments.

Frequently asked questions

What are the equivalent or alternative parts for SN74CBTLV3125RGYR?

The 74CBTLV family includes other bus switch configurations, but a direct drop-in replacement from another vendor would require verifying the pinout and electrical characteristics against the TI datasheet.

Can SN74CBTLV3125RGYR be used for bidirectional signal switching?

Yes — the bus switch architecture is bidirectional. When the switch is enabled (OE low), signals pass in either direction between the A and B ports with the same low on-state resistance. This makes it suitable for multiplexing data buses, I2C lines, or GPIO expansion where direction changes during operation.
