Housed in a SOT-23-5 package, the part occupies minimal board area. The five-pin layout includes the switch I/O (A, B), supply (VCC), ground (GND), and active-low enable (OE).
No end-of-life notification or last-time-buy schedule is in effect. For dual-sourcing resilience, the 74CBT family has multiple pin-compatible bus switches from TI and other vendors — qualify an alternate now if the BOM calls for a single-sourced line.
Yes, the part is designed for a single 4.5V to 5.5V supply and passes 5V signals directly. Control inputs are referenced to VCC, so 5V logic is required for reliable enable switching.
