MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low power consumption. This multiplexer
features both true (Y) and complement (W) outputs
as well as STROBE input. The STROBE must be a
low logic level to enable this device. When the
STROBEinput is high, both outputs are in the high
impedance state. When enabled, address informa-
tiononthedata selectinputs determines whichdata
input is routed to Y and W. All inputs are equipped
with protection circuits against static discharge and
transient excess voltage.
