M74HC4852 DUAL 4 Channel Analog Mux/Demux With Injection Current Protection

The M74HC4852 is a dual four-channel analog multiplexer/demultiplexer manufactured with silicon gate C2MOS technology. It is pin-to-pin compatible with the equivalent to standard HC4052 and MC14052, but features injection current effect control. This makes the device particularly suited for use in automotive applications where voltages in excess of normal logic voltage are common. The injection current effect control allows signals at disabled input channels to exceed the supply voltage range or go down to ground without affecting the signal of the enabled analog channel.

This eliminates the need for external diode-resistor networks typically used to keep the analog channel signals within the supply voltage range.

This analog switch is bidirectional and digitally controlled. It has two binary control inputs A and B to select 1 of 4 to be turned on, and connected to the output, and a INH input to disable all channels. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage
