Analog Multiplexers/
Demultiplexers with
Injection Current Effect
Control with LSTTL
Compatible Inputs
Automotive Customized
This device is pin compatible to standard HC4051 and MC14051B
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
or LSTTL outputs.
Features
• Injection Current Cross−Coupling Less than 1mV/mA (See Figure 4)
• Pin Compatible to HC4051 and MC14051B Devices
• Power Supply Range (V_CC − 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
• These are Pb−Free Devices*
