Bus switch for signal routing in mixed-voltage boards
The SN74CBTLV3125D is a 4-bit bus switch from TI's 74CBTLV family, each channel a 1:1 pass-FET that connects or isolates a digital signal path under logic control. Four independent switches in one 14-SOIC package replace discrete FETs or jumper headers on a dense board — the 0.154-inch-wide body fits a standard SOIC footprint with 1.27 mm pin pitch.
Supply range and temperature grade for industrial use
Because it is a bus switch (not a level translator), the signal voltage on the A and B ports must stay within the supply range — the part does not shift levels, it just connects or disconnects.
Active lifecycle and compliance
ROHS3 compliant and free of the six original RoHS substances plus four phthalates — no exemption declarations needed for EU-market builds. No REACH SVHC or conflict-minerals data is carried in this listing.
