The SN74BCT25240 is a 25-Ω octal buffer/driver with 3-state outputs. It features state-of-the-art BiCMOS design that significantly reduces ICCZ. The ESD protection exceeds 2000V per MIL-STD-883C, Method 3015, and exceeds 200V using the machine model (C=200pF, R=0). It is designed to facilitate incident-wave switching for line impedances of 25Ω or greater. The distributed VCC and GND pins minimize noise generated by the simultaneous switching of outputs. This product is specifically designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It is capable of sinking 188mA IOL, which facilitates switching 25Ω transmission lines on the incident wave. When the output-enable (1OE and 2OE) inputs are low, the device transmits the inverted A-input data to the Y outputs. When 1OE and 2OE are high, the outputs are in the high-impedance state. The SN74BCT25240 is characterized for operation from 0°C to 70°C.
