Functional Description

• Triple 2-Channel Analog Multiplexer/Demultiplexer

General

The 74HCT4053D are high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricated with silicon

gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining

the CMOS low power dissipation.

This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. This inputs

are compatible with TTL, NMOS and CMOS output voltage levels.

The 74HCT4053D has a 2 channel × 3 configuration.

The digital signal to the control terminal turns ON the corresponding switch of each channel a large amplitude

signal (VCC - VEE) can then be switched by the small logical amplitude (VCC - GND) control signal.

For example, in the case of VCC = 5 V, GND = 0 V, VEE = -5 V, signals between -5 V and +5 V can be switched

from the logical circuit with a single power supply of 5 V. As the ON-resistance of each switch is low, they can be

connected to circuits with low input impedance.

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