10-channel bus switch for 5 V signal isolation
The SN74CBT3861DW is a 10-bit bus switch from TI's 74CBT family, configured as 10 independent 1:1 SPST switches. Each switch presents a low ON-state resistance between the A and B ports when the corresponding output-enable pin is asserted, effectively connecting or isolating two signal nodes with minimal propagation delay.
The 1.27 mm pin pitch is rework-friendly with a fine-tip iron or hot-air station; no special stencil or profile needed beyond the standard JEDEC MSL-1 bake-out if the tube seal is intact.
