Automotive Customized
MC74HC4851A, MC74HC4852A, MC74HCT4851A, MC74HCT4852A
These devices are pin patible to standard HC405x and MC1405xB analog mux/demux devices, but feature injection current effect control. This makes them especially suited for usage in automotive applications where voltages in excess of normal logic voltage are mon.
The injection current effect control allows signals at disabled analog input channels to exceed the supply voltage range without affecting the signal of the enabled analog channel. This eliminates the need for external diode/resistor networks typically...
