The SL74HC4052 is a high-performance silicon-gate CMOS analog multiplexer/demultiplexer from System Logic Semiconductor SLS. It achieves fast propagation delays, low ON resistances, and low OFF leakage currents. This product controls analog voltages that may vary across the complete power supply range (from VCC to VEE). 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 LS/ALS TTLoutputs.
