SCBS101B − JUNE 1990 − REVISED NOVEMBER 1993
DW OR NT PACKAGE
This 25-Ω octal buffers and line driver is designed specifically to improve both the performance and density of
3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The SN74BCT25240 is capable of sinking 188-mA IOL, which facilitates switching 25-Ω transmission lines on
the incident wave. The distributed VCC and GND pins minimize switching noise for more reliable system
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. 1OE affects only the 1Y
outputs; 2OE affects only the 2Y outputs.
The SN74BCT25240 is characterized for operation from 0°C to 70°C.
