It combines one direction-control input with an output-enable pin, letting you isolate or connect an 8-bit bus segment on the fly. The 32 mA source / 64 mA sink output drive gives it the muscle to drive heavily loaded backplanes or memory-array address lines without external buffers. ## Industrial temperature and SOIC-24 footprint The 24-SOIC package with 0.295-inch body width and 7.50 mm pitch is a standard footprint — easy to hand-solder or rework with hot air, and widely supported by PCB layout libraries. The wide body also helps with visual inspection of the 3-state control traces after assembly.","metaTitle":"CY74FCT646CTSOC 74FCT Transceiver, 8-Bit, 3-State, 24-SOIC","metaDescription":"CY74FCT646CTSOC 8-bit non-inverting transceiver with 3-state outputs. 32 mA source / 64 mA sink.
