SN74HC4852-Q1

DUAL 4-TO-1 CHANNEL ANALOG MULTIPLEXER/DEMULTIPLEXER

WITH INJECTION-CURRENT EFFECT CONTROL

SCLS705A – DECEMBER 2006 – REVISED FEBRUARY 2008

www.ti.com

• Qualified for Automotive Applications

• Injection-Current Cross Coupling <1 mV/mA

(see Figure 1 )

• Low Crosstalk Between Switches

• Pin Compatible With SN74HC4052,

SN74LV4052A, and CD4052B

• 2-V to 6-V V

Operation

This dual 4-to-1 CMOS analog multiplexer/demultiplexer is pin compatible with the 4052 function and also

features injection-current effect control. This feature 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.
