M74HC4852 Dual 4:1 channel analog MUX/DEMUX with injection current protection Datasheet production data Features Low power dissipation I = 2 A (max.) at T = 25 C CC A Injection current protection: V out < 1 mV at V = 5 V, I = 1 mA, R = 3.9 k CC IN S ON resistance at T = 25 C A SO-16 215 typ. (V = 3.0 V) CC 160 typ. (V = 4.5 V) CC 150 typ. (V = 6 V) CC Fast switching: t = 8.6 ns (typ.) at T = 25 C, pd A V = 4.5 V CC Description Wide operating supply voltage range The M74HC4852 device is a dual four-channel V = 2 V to 6 V CC analog multiplexer/demultiplexer manufactured High noise immunity: V = V = 28% V 2 NIH NIL CC with silicon gate C MOS technology. (min.) It features injection current effect control which Pin and function compatible with series 4052, makes the device particularly suited for use in 4852 automotive applications where voltages in excess Latch-up performance exceeds 500 mA of normal logic voltage are common. The (JESD 17) injection current effect control allows signals at disabled input channels to exceed the supply ESD performance voltage range or go down to ground without HBM: 2000 V affecting the signal of the enabled analog MM: 200 V channel. CDM: 1000 V This eliminates the need for external diode- resistor networks typically used to keep the Applications analog channel signals within the supply voltage range.
