Features

Description

• Buffered Inputs

The CD54/74FCT245 octal bus transceiver uses a small

geometry BiCMOS technology. The output stage is a combi-

nation of bipolar and CMOS transistors that limits the output

• Typical Propagation Delay: 5.0ns at V

ringing (a source of EMI) and minimizes V

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.

• Speed of Bipolar FAST™/AS/S

• 64mA Output Sink Current (74 Series)

• 48mA Output Sink Current (54 Series)

The CD54/74FCT245 is a noninverting, three-state, bidirec-

tional 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 direc-

tion. When the Output Enable input is HIGH, the outputs are in

the high impedance state.

• Output Voltage Swing Limited to 3.7V at V

• Controlled Output Edge Rates

= 5V

• Input/Output Isolation to V

• BiCMOS Technology with Low Quiescent Power
