DESCRIPTION
The M74HC354 is an high speed CMOS 8
(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 inputs G1,
G2 are held high or input G3 is held low. This
device is suitable for interfacing with bus lines in a
bus organized system.
The M74HC354 is similar in function to the
M74HC356, which has an 8-bit flip-flop as the data
register instead of an 8-bit latch.
CHANNEL
MULTIPLEXER/REGISTER
2
(3-STATE) fabricated with silicon gate C MOS
technology.
This device contains an
8 channel digital
multiplexer with an 8-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
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
