† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. The input and output voltage ratings may be exceeded if the input and output current ratings are  bserved.

2. This value is limited to 5.5 V maximum.

3. The package thermal impedance is calculated in accordance with JESD 51-7.


Description

This eight-channel CMOS analog multiplexer/demultiplexer SN74HC4851-Q1  is pin compatible with the '4051 function and,  additionally, features injection-current effect control, which has excellent value in automotive applications where voltages in excess of normal supply voltages are common.

The injection-current effect control allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel. SN74HC4851-Q1 eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range.
