Among the broad range of integrated circuit products available today, Interface - Analog Switches, Multiplexers, Demultiplexers products are particularly widespread. The DG212CJ is a great example of such product and it has active low enable feature incorporated. This device features two 2-channel Analog Multiplexers/Switches with logic level enable control pin. The DG212CJ ensures low ON-resistance flatness, low propagation delay and low power consumption. It is perfect for input protection and multiplexing/switching applications.

DG212CJ Application Field and Working Principle

The DG212CJ can be used in multiplexing applications, input protection, data acquisition systems, signal switching and buffering, level translation and instrumentation. This device is available in the three different packages SC-70, SOT-23 and TSSOP. Maximum supply voltage of the DG212CJ is 6V, which reduces the need for level translators. The logic level enable control enables you to switch quickly and control the operation of the device.

The DG212CJ consists of two switching networks with each having two switches. When it is off, the switches floats and they go to “High-Z” state. When the enable pin is taken LOW, the switches connect their respective channel inputs to their channel outputs. The anode and cathode of both the switches are given common enable control and hence the two switches enable or disable together. This device works on the principle of “LOW logic enable control”, meaning that it is enabled when the logic level enable control pin is at logic 0.

DG212CJ Features

The DG212CJ is ideal for multiplexing applications. It has an ON-resistance flatness of 0.3 Ohm and vice impressive propagation delay of 6ns. This means that it switches quickly and the flatness of ON-resistance ensures that there is no distortion in the signal. It has a power consumption of just 2.6μA and operates at a maximum voltage of 6V. All these features make this device apt for multiplexing applications.

Conclusion

DG212CJ is part of the Interface - Analog Switches, Multiplexers and Demultiplexers family and is a high-performance 2-channel Analog Multiplexer/Switch with logic level enable control pin. It has low power consumption, high speed switching and low distortion levels. This device can be used in multiplexing, buffering, instrumentation and level translation applications and is available in three packages. All these features of the DG212CJ make it ideal for applications where a small multiplexer with low distortion is required.
