descriptionThe CD74FCT245 is an octal bus transceiver with 3-state outputs using a small-geometry BiCMOS technology.
The output stages are a combination of bipolar and CMOS transistors that limit the output high level to two diode
drops below VCC. This resultant lowering of output swing (0 V to 3.7 V) reduces the power-bus ringing [a source
of electromagnetic interference (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 mA.
The CD74FCT245 allows data transmission from the A bus to the B bus or from the B bus to the A bus,
depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used
to disable the device so that the buses are effectively isolated.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The CD74FCT245 is characterized for operation from 0°C to 70°C.
