SN74HC4851
- Injection-current cross coupling <1mV/mA (see in Application Information)
- Low crosstalk between switches
- Terminal compatible with SN74HC4051, SN74LV4051A, and CD4051B devices
- 2V to 5.5V VCC operation
- Latch-up performance exceeds 100mA per JESD 78, class II
This eight-channel CMOS analog multiplexer/demultiplexer is terminal compatible with the function of the ’4051 device, and 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 feature eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range.
