The 74FCT16543ATPVG: This is a 16-bit non-inverting transceiver built from two 8-bit elements, each with its own direction and output-enable controls. The 3-state outputs let the device isolate from the bus when disabled — useful for shared data lines where multiple drivers contend for the same traces. Output drive is rated 32 mA source and 64 mA sink, enough to drive a moderate backplane or memory bus without external line drivers.
The supplier device package is designated 56-SSOP.
The transceiver can source 32 mA and sink 64 mA per output. This drive strength is sufficient for driving moderate bus loads without external buffering.
