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.
