IDTQS74FCT2541T/AT/CT
DESCRIPTION:
The IDTQS74FCT2541T is an 8-bit buffer/line driver with 3-state
outputs and a 25鈩?resistor output , ideal for driving transmission lines and
reducing system noise. The 2540 series parts can replace the 540 series
to reduce noise in an existing design. All inputs have clamp diodes for
undershoot noise suppression. All outputs have ground bounce suppres-
sion. Outputs will not load an active bus when Vcc is removed from the
device.
