Description

The CD74FCT541 is an octal buffer/driver with 3-state outputs that is ideal for driving bus lines or buffer memory address registers and uses 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 (0 V to 3.7 V) reduces power-bus ringing [a source of electromagnetic interference (EMI)] and minimizes VCCbounce and ground bounce and their effects during simultaneous output switching. The output configuration also enhances switching speed and is capable of sinking 64 mA. The 3-state control gate is a two-input AND gate with active-low inputs, so that if either output-enable (OE1\ or OE2\) input is high, all corresponding outputs are in the high-impedance state. The outputs provide noninverted data when they are not in the high-impedance state. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The CD74FCT541 is characterized for operation from 0°C to 70°C.
