MC74HC4851A,
MC74HC4852A
Analog Multiplexers/
Demultiplexers with
Injection Current Effect
Control
Automotive Customized
These devices are pin compatible to standard HC405x and
MC1405xB analog mux/demux devices, but feature injection current
effect control. This makes them especially suited for usage in
automotive applications where voltages in excess of normal logic
voltage are common.
The injection current effect control allows signals at disabled analog
input channels to exceed the supply voltage range 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.
The devices utilize low power silicon gate CMOS technology.
The Channel Select and Enable inputs are compatible with standard
CMOS outputs.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.

TSSOP Package: −6.1 mW/°C from 65° to 125°C
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance cir-
cuit. For proper operation, V
in
and
V

should be constrained to the
range GND

Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V

).
Unused outputs must be left open.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond
the Recommended Operating Ranges limits may affect device reliability.
*For voltage drops across switch greater than 1.2 V (switch on), excessive V
CC
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 will be unaffected unless the Maximum Ratings are exceeded.
