资 源 简 介
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 VCC. This resultant lowering of output swing (0 V to 3.7 V) reduces power-bus ringing [a source of electromagneTIc interference (EMI)] and minimizes VCC 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.
