DESCRIPTION
The M54/74HC354 is a high speed CMOS 8-CHAN-
NEL MULTIPLEXER/REGISTER (3-state) fabri-
cated in silicon gate C2MOS technology. It has the
same high speed performance of LSTTL combined
with true CMOS low consumption.
This device contains an 8 channel digital multiplexer
with an 8-bit input data register and a 3-bit address
input register with 3-state outputs. The one of eight
input data will be provided on the Y output pin (non-
inverted output) and W output pin (inverted output)
determined by the address data.
The information at the data inputs (D0 to D7) is
stored in the 8-bit latch at the negative pulse on DC
input. The information at the address inputs (S0 to
S2) is stored in the 3-bit latch at the negative pulse
on SC input. These outputs are disabled to be high-
impedance when input G1 is held high, input G2 is
held high or input G3 is held low. This device is suit-
able for interfacing with bus lines in a bus organized
system.
The M54/74HC354 is similar in function to the
M54/74HC356, which has an 8-bit flip-flop as the
data register instead of an 8-bit latch. All inputs are
equipped with protection circuits against static dis-
charge and transient excess voltage.
