说明

The CD74FCT623 is an octal bus transceiver that uses a small-geometry BiCMOS technology. The output stage is a combination of bipolar and CMOS transistors that limits the output high level to two diode drops below V_CC. This resultant lowering of output swing (0 V to 3.7 V) reduces power-bus ringing [a source of electromagnetic interference (EMI)] and minimizes V_CC bounce and ground bounce and their effects during simultaneous output switching. The output configuration also enhances switching speed and is capable of sinking 64 mA.

This device is a noninverting, 3-state, bidirectional transceiver-buffer intended for two-way transmission from A bus to B bus or B bus to A bus, depending on the logic levels of the output-enable (OEAB, OEBA\) inputs.
