MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Demultiplexers Analog Multiplexers/ MC54/74HC4051A MC74HC4052A MC54/74HC4053A High–Performance Silicon–Gate CMOS The MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A 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 R on of metal–gate CMOS analog switches. For a multiplexer/demultiplexer with channel–select latches, see HC4351A. 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 Improved Linearity and Lower ON Resistance Than Metal–Gate Counterparts Low Noise In Com……
