Table 1.
The M74HC4852 device is a dual four-channel
analog multiplexer/demultiplexer manufactured
with silicon gate C2MOS technology.
It features injection current effect control which
makes the device particularly suited for use in
automotive applications where voltages in excess
of normal logic voltage are common. The
injection current effect control allows signals at
disabled input channels to exceed the supply
voltage range or go down to ground without
affecting the signal of the enabled analog
channel.
This eliminates the need for external dioderesistor networks typically used to keep the
analog channel signals within the supply voltage
range.

1. For voltage drops across the switch greater than 1.2 V (switch on), excessive VCC current may be drawn; i.e., the current
out of the switch may contain both V CC and switch input components. The reliability of the device is unaffected unless the
maximum ratings are exceeded.

1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current
consumption without load (refer to Figure 5). The average operating current can be obtained by the following equation:
ICC (opr.) = CPD x VCC x fIN + ICC /8.

Typical values are measured at TA = 25 °C. They are calculated as the difference from VOUT without injection current and
VOUT with injection current. IIN = total current injected into any other disabled channels, one at time.
