The TC74VHC153 is an advanced high speed CMOS DUAL
4-CHANNEL MULTIPLEXERs fabricated with silicon gato
C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
Each of these data (1C0-1C3, 2C0-2C3) is selected by the
two address inputs A and B.
Separate strobe inputs (1G, 2G) are provided for each of the
two four-line sections.
The strobe input (G) can be used to inhibit the data output;
the output is fixed in low level while the strobe input is held
high.
An input protection circuit ensures that 0 to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched
supply and input voltages.
