DESCRIPTION
These devices are analog multiplexer demultiplexers in high speed silicon gate C 2MOS technology and they are pin compatible with the equivalent metal gate CMOS ”4000B” series. These analog switches are bidirectional and digitally PIN CONNECTION (top view) HC4051 controlled. A built-in level shifting is included to allow them an input range of up to ± 6V (peak) for an analog signal with digital control signal of 0 to 6V. VEE supply pin is provided for analog input signals. They have an inhibit (INH) input terminal to disable all the switches when high. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND. HC4052 HC4053 October 1993 1/15 M54/M74HC4051/4052/4053 DESCRIPTION
