octal Buffers Line Drivers
use 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 64 milliamperes. The CD74FCT540
is a three-state Buffer
having two active LOW output enables. The CD74FCT541
is a noninverting three state Buffer
having two active LOW output enables.
