It contains two 8-bit elements, each with independent direction and output-enable controls, and drives 3-state buses with 32 mA sink and 64 mA source capability across a 4.5 V to 5.5 V supply range. The industrial temperature grade (-40°C to 85°C) suits it for factory-floor control, telecom line cards, and other environments where the ambient temperature swings beyond commercial limits. ## Output drive — what 32 mA / 64 mA means on the bus The asymmetric drive — 32 mA for a logic high, 64 mA for a logic low — is typical of 74FCT transceivers and reflects the higher current needed to discharge bus capacitance quickly. In a backplane or memory-bank interface, that 64 mA low-level drive lets you fan out to more than 10 LSTTL loads per line without degrading the VOL margin. If your BOM currently uses a transceiver with lower drive (15 mA or 24 mA), swapping to this part buys you extra fan-out headroom without a board respin, provided the package footprint matches. ## Package and footprint: 56-SSOP (7.50 mm) The 56-SSOP package with 0.295-inch (7.50 mm) body width uses a standard 0.635 mm pitch. The supplier device package is listed as 56-SSOP, which is the same mechanical outline as a 56-pin shrink small-outline package. The shipping medium is Tube, so if your pick-and-place line expects tape-and-reel, factor in a tube-to-tape transfer or check whether a reeled variant exists under a different ordering code. The mounting type is surface mount, and the part is ROHS3 compliant, which eliminates any lead-free process conflict. ## Lifecycle and compliance The CY74FCT16543CTPVC carries an Active product status, meaning Cypress (now part of Infineon) continues to manufacture it with no announced last-time-buy. ROHS3 compliance is confirmed, covering the full ten restricted substance categories plus the four phthalates. No AEC-Q automotive qualification is listed on this entry, so it is not formally graded for under-hood or chassis-domain use — keep it in industrial and commercial equipment where the -40°C to 85°C ambient range is sufficient.","metaTitle":"CY74FCT16543CTPVC 74FCT Transceiver, 56-SSOP, 4.5V-5.5V","metaDescription":"CY74FCT16543CTPVC is an active 74FCT-series 16-bit non-inverting transceiver with 3-state outputs. 32mA/64mA drive, -40°C to 85°C, 56-SSOP.
