The MC54/74HC4051, MC74HC4052 and MC54/74HC4053 utilize silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/demultiplexers control analog voltages that may vary across the complete power supply range (from VCC to VEE).
●The HC4051, HC4052 and HC4053 are identical in pinout to the metal–gate MC14051B, MC14052B and MC14053B. The Channel–Select inputs determine which one of the Analog Inputs/Outputs is to be connected, by means of an analog switch, to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off. The Channel–Select and Enable inputs are compatible with standard CMOS outputs; with pullup resistors they are compatible with LSTTL
●outputs. These devices have been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal–gate CMOS analog switches.
●For multiplexers/demultiplexers with channel–select latches, see HC4351, HC4352 and HC4353.
