DESCRIPTION
The M54/74HC356 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)
is determineted by the address data.
The information at the data inputs (D0 to D7) is
stored in the 8-bit flip-flop at the positive going edge
of clock input (CLOCK). The information at the ad-
dress 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 suitable for interfacing with bus
lines in a bus organized system. The M54/74HC356
is similar in function to the M54/74HC354, which has
an 8-bit latch as the data register instead of an 8-bit
flip-flop. All inputs are equipped with protection cir-
cuits against static discharge and transient excess
voltage.
