Analog switches, multiplexers, and demultiplexers are essential components in many electronics circuits, and the SN74HC4066DG4 is one such device. It is a Quad Bilateral Switch and can be used in applications where signals need to be isolated (or multiplexed) between a single input and multiple output channels. This enables a single signal (or multiple signals) to be transmitted from a single source to different destinations. Other uses include implementing logic circuits, creating analog delay lines, and sampling and holding signals.

Overview

The SN74HC4066DG4 is a general purpose analog switch designed for use in digital electronics. It is not suitable for applications where high voltage or current needs to be switched. It is available in a 4-pin plastic DIP package and operates over a wide temperature range. The device’s input and output pin configurations are designed to connect directly with other circuitry for convenient signal routing. The SN74HC4066DG4 has an analog bandwidth of up to 10MHz and can handle current up to 24mA and voltage up to 15V.

Features

• High speed (t_on max = 33ns)
• Low Crosstalk (–83dB @ 10MHz)
• Quiescent current of 0.09mA/channel
• Low On-resistance (Typically 150 ohms)
• Low Off-resistance (Typically 600 ohms)
• Low Power PVT-Compatible Logic

Working Principle

The SN74HC4066DG4 is a Quad Bilateral Switch, meaning it can selectively route signals between one input and four outputs. It is controlled by five input pins—Enable on A (ENA) and B (ENB), and four select pins (A0 – A3). When the Enable pins are in the HIGH (1) state, the corresponding select pins control which of the four output channels (Y0 – Y3) is connected to the input (IN). When in the LOW (0) state, all four output channels are disconnected from the input. The multiplexer has an On/Off switch on each channel that can be used to turn each output on and off independently of the others.

Applications

The SN74HC4066DG4 has wide range of applications, due to its ability to route signals between a single input and multiple outputs. It can be used for signal isolation in multiplexed digital circuits, where a signal needs to be routed from a single source to multiple destinations. Its ability to act as a digital switch also makes it suitable for creating logic circuits, analog delay lines, and sampling and holding signals. Other applications include low-power control systems, interface logic, and signal routing in CDMA/TDMA/DAMA radio systems.

Conclusion

The SN74HC4066DG4 is a Quad Bilateral Switch that is especially suited for applications that require signal isolation between one input and multiple outputs. It has fast switching speeds, low crosstalk and quiescent currents, high input and output impedance, and high off-resistance. Its low power PVT-compatible logic makes it suitable for many electronics applications, such as signal isolation, multiplexing, sampling and holding, and analog delay lines. It is an essential component for many digital circuits.
