Features, Applications
SN74HC4851 8CHANNEL ANALOG MULTIPLEXER/DEMULTIPLEXER WITH INJECTIONCURRENT EFFECT CONTROL

(see Figure 1) Low Crosstalk Between Switches Pin Compatible With SN74HC4051, SN74LV4051A, and to 6-V VCC Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II ESD Protection Exceeds JESD - 2000-V Human-Body Model - 200-V Machine Model - 1000-V Charged-Device Model (C101)

This eight-channel CMOS analog multiplexer/demultiplexer 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. This eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range. ORDERING INFORMATION

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 observed. 2. This value is limited 5.5 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51-7.
