16-bit bus transceiver, FCT series, through-hole
The CY74FCT16952ETPVC is a 16-bit bidirectional bus transceiver in the FCT (Fast CMOS TTL-compatible) series. It provides 3-state outputs on both A and B ports, allowing direct connection to a shared data bus without external bus-hold logic. The through-hole package — a standard DIP footprint — suits legacy backplanes, prototyping boards, and applications where a socketed part is preferred for rework or field replacement.
RoHS non-compliant — legacy lead-bearing finish
This part is marked RoHS non-compliant, meaning the termination finish contains lead. That is a deal-breaker for new designs targeting RoHS exemption-free markets, but it is the correct fit for military, aerospace, or industrial BOMs that require a tin-lead solder finish for reliability in high-vibration or thermal-cycling environments. The lead-bearing finish also reflows at a higher temperature than SAC alloys, so the rework profile differs from a standard lead-free joint.
