2.7-3.6 V supply — 24 mA symmetrical drive
The CY74FCT163H245CPAC: Each of the 16 I/O lines sources or sinks 24 mA, a symmetrical drive strength that lets it fan out to multiple CMOS or TTL loads on a backplane without adding bus-hold buffers. The 24 mA output current at both high and low states is higher than typical 3.3 V bus transceivers (often 8-12 mA), which means the part can drive longer traces or more loads before signal integrity degrades. For a 16-bit data bus in a mid-speed control system, this single part replaces two 8-bit transceivers, saving board area.
Industrial temperature — 48-TSSOP footprint
The 48-TFSOP body (6.10 mm wide, 0.50 mm pitch) ships in the 48-TSSOP supplier package — a common footprint for 16-bit bus logic that lets a single PCB layout serve multiple transceiver vendors. The 0.50 mm pitch on the 48-TSSOP package demands a controlled-impedance PCB stack-up for the bus lines running at higher edge rates. The narrow body (6.10 mm) limits fan-out of the inner rows; a four-layer board is typical for routing all 16 I/O pairs plus the control signals cleanly.
RoHS non-compliant — compliance flag for EU markets
Infineon lists this part as RoHS non-compliant. For BOMs destined for EU or other RoHS-restricted markets, the buyer must verify whether an exemption applies (e.g., lead in ceramic packages for high-reliability applications) or plan a drop-in RoHS-compliant alternative from the same FCT family.
