The 74CB3Q3306ADCURE4 is a logic device that is classified as a signal switch, multiplexer, or decoder. It is a multi-channel general purpose switch designed to help route signals within a digital system. It can be used for a variety of applications ranging from multiplexing signals for controlling LEDs and displays to diversifying signals for voice storage and retrieval.

The 74CB3Q3306ADCURE4 operates on both half-duplex and full-duplex modes, providing improved channel switching flexibility. It is a monolithic device with low standby power dissipation and high-speed operation, yet it has a low-power design and a maximum propagation delay of only 5ns for three-state outputs. With built-in protection features, it is highly reliable and features ESD protection, latchup protection, and overvoltage tolerance up to +24V.

The 74CB3Q3306ADCURE4 is an 8-channel switch with a common-channel enable (ECD) input, 6 data inputs (DI0 to DI5), and 6 output channels (Q0 to Q5). It has three control signals – ECD, ENA (enable) and ENB (enable) – that are used to select the channel that is to be switched on.

The working principle of the 74CB3Q3306ADCURE4 is quite simple. When the ECD is low, the ENA or ENB signal is driven low to select the channel to be enabled. When the ECD signal is low, the data input DI0 to DI5 is routed out to the selected output channel (Q0 to Q5). When ECD is high, both ENA and ENB are ignored and all outputs are disabled. The Q outputs can also be used in open drain/collector mode.

The device can be used in a variety of applications such as LED and display control, I/O Port isolation, signal diversion, signal routing and multiplexing, and voice storage and retrieval. It can also be used as a level-switching device to steer digital signal levels to different nodes. It is highly reliable with low power consumption and low propagation delay, providing greater signal control flexibility with robust protection against voltage overload and ESD.
