TECHNICAL DATA
IN74HC4051A
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The IN74HC4051A 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 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/ALSTTL outputs. Fast Switching and Propagation Speeds Low Crosstalk Between Switches Diode Protection on All Inputs/Outputs Analog Power Supply Range (VCC-VEE)=2.0 to 12.0 V Digital (Control) Power Supply Range (VCC-GND)=2.0 to 6.0 V Low Noise
