Functional Description

? Dual 4-Channel Multiplexer

General

The 74VHC153FT is an advanced high speed CMOS DUAL 4-CHANNEL MULTIPLEXERs fabricated with

silicon gate 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 5.5 V can be applied to the input pins without regard to the supply

voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.

This circuit prevents device destruction due to mismatched supply and input voltages.
