1 / 7 page 8-1 Data sheet acquired from Harris Semiconductor SCHS257 Features • Buffered Inputs • Typical Propagation Delay: 6.4ns at VCC = 5V, TA = 25 oC, C L = 50pF • CD74FCT540 - Inverting • CD74FCT541 - Noninverting • SCR Latchup Resistant BiCMOS Process and Circuit Design • Speed of Bipolar FAST™/AS/S • 64mA Output Sink Current • Output Voltage Swing Limited to 3.7V at VCC = 5V • Controlled Output Edge Rates • Input/Output Isolation to VCC • BiCMOS Technology with Low Quiescent Power 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 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. Ordering Information Pinouts PART NUMBER TEMP. RANGE (oC) PACKAGE PKG. NO.
