M74HC253 Dual 4-Channel Multiplexer (3-State)

The M74HC253 is an high speed CMOS DUAL 4 CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology.

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 (nG) can be used to inhibit the data output; the output of M74HC253 is a high impedance while the strobe input is held high.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.
