HC4053A - 156 FETs or 39 Equivalent GatesPinoutDescriptionThe MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A utilize silicongate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/ demultiplexers control analog voltages, MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A may vary across the complete power supply range (from V
CC to V
EE).
The HC4051A, HC4052A and HC4053A are identical in pinout to the metalgate MC14051AB, MC14052AB and MC14053AB. The ChannelSelect 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 ChannelSelect and Enable inputs of MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A are compatible with standard CMOS outputs; with pullup resistors they are compatible with LSTTL outputs.
MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A have been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metalgate CMOS analog switches.
