The CD54/74FCT245 octal bus transceiver 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 (0V to 3.7V) reduces power bus ringing (a source of 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 48mA to 64mA. The CD54/74FCT245 is a noninverting, three-state, bidirectional transceiver/buffer intended for two-way transmission from"A" bus to "B" bus or "B" bus to "A" bus. The logic level present on the Direction Input (DIR) determines the data direction. When the Output Enable input is HIGH, the outputs are in the high impedance state. |
