Active production, single-supply bus switch for 5V logic paths
The CBT16211DL,518: The device switches 12 signal channels in a 1:1 configuration, organized as two independent 6-bit banks. Each bank is controlled by its own enable pin, letting you isolate or connect two 5V logic buses independently without adding propagation delay from a standard logic gate.
56-SSOP footprint and layout considerations
The supplier device package is 56-SSOP — the two designations refer to the same footprint. Surface-mount assembly requires a standard reflow profile for SSOP; the 0.65 mm pitch is within the capability of most PCB fabs without via-in-pad. Because this is a bus switch with low on-resistance (typical 5-7 ohms for the 74CBT family), the PCB trace resistance between the switch and the target bus matters more than the switch itself. Keep the trace length under 50 mm from the package pin to the connector or memory device to avoid adding RC delay that degrades signal integrity.
Sourcing and compliance for the BOM line
The CBT16211DL,518 is ROHS3 compliant (EU 2015/863), which covers the full ten restricted substances including the four phthalates. No pin-compatible second source or official cross-reference is recorded for this specific order code.
