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.

•Injection Current Cross±Coupling Less than 1mV/mA (See Figure 9)

•Pin Compatible to HC405X and MC1405XB Devices

•Power Supply Range (VCC ± GND) = 2.0 to 6.0 V

•In Compliance With the Requirements of JEDEC Standard No. 7A

•Chip Complexity: 154 FETs or 36 Equivalent Gates

						Unused outputs must be left open.

*Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.

²Derating Ð Plastic DIP: ± 10 mW/ _C from 65_ to 125_C SOIC Package: ± 7 mW/_C from 65_ to 125_C

TSSOP Package: ± 6.1 mW/_C from 65_ to 125_C

For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor High±Speed CMOS Data Book (DL129/D).

RECOMMENDED OPERATING CONDITIONS

Symbol		Parameter				Min	Max	Unit
VCC	Positive DC Supply Voltage		(Referenced to GND)			2.0	6.0	V
Vin	DC Input Voltage (Any Pin)		(Referenced to GND)			GND	VCC	V
VIO*	Static or Dynamic Voltage Across Switch					0.0	1.2	V
TA	Operating Temperature Range, All Package Types					± 55	+ 125	_C

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