It is pin to pin compatible with the equivalent to standard HC4051 and MC14051, but feature injection current effect control. This make this device especially suited for usage in automotive applications where voltages in excess of normal PIN CONNECTION AND IEC LOGIC SYMBOLS logic voltage are common. The injection current effect control allows signals at disabled input channels to exceed the supply voltage range or go down ground without affecting the signal of the enabled analog channel. This eliminated 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 have three binary control inputs A, B, and C to select 1 of 8 to be turned on, and connected to the output, and a INH input to disable all channel. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
