Analog Multiplexers / Demultiplexers
High−Performance Silicon−Gate CMOS

The MC74HC4051A, MC74HC4052A and MC74HC4053A 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 HC4051A, HC4052A and HC4053A are identical in pinout to the metal−gate MC14051AB, MC14052AB and MC14053AB. 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 a multiplexer/demultiplexer with injection current protection, see HC4851A and HC4852A.
