Hot-selling and scarce CD74FCT241TM FCT Interface Logic Octal Buffers/Line Drivers, Three-State SOP spot stock

Product Descriptions

The CD54/74FCT240, 240AT, 241, 244 and 244AT threestate 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 48mA to 64mA.

​

The CD54/74FCT240, 240AT, 244 and 244AT have activeLOW output enables (1OE, 2OE). The CD54/74FCT241 and CD54/74FCT241AT have one active-LOW (1OE) and one active-HIGH (2OE) output enable.
