DESCRIPTION:
The IDT74FCTL2257T is a 25
resistoroutputversionofahigh-speed
CMOS TTL-compatible, quad, 2-input multiplexer, useful for driving trans-
mission lines and reducing system noise. 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.
