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.","metaTitle":"NXP CBT16211DL,518 Bus Switch, 12 x 1:1, 56-SSOP, Active","metaDescription":"NXP CBT16211DL,518 Bus Switch, 74CBT series, 12 x 1:1 circuit, 4.5V-5.5V supply, -40°C to 85°C, 56-SSOP.

Typical applications include memory bank switching, hot-swap bus isolation, and signal routing in microcontroller or processor systems where zero propagation delay is required — the switch passes the signal with only a few ohms of on-resistance rather than the gate delay of a logic buffer."},{"question":"What is the closest pin-compatible alternative to the CBT16211DL,518?","answer":"No pin-compatible alternative or official second source is recorded for this specific order code. The 74CBT series includes other bus switches with different channel counts or package options, but none is documented as a direct drop-in replacement for the 56-SSOP CBT16211DL,518.
