Description
The CD74FCT540 and CD74FCT541 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
V
CC
. This resultant lowering of output swing (0V to 3.7V)
reduces power bus ringing (a source of 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 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.
