The MM74HC4051, MM74HC4052 and MM74HC4053multiplexers are digitally controlled analog switches implemented in advanced silicon-gate CMOS technology. These switches have low "on" resistance and low "off" leakages. They are bidirectional switches, thus any analog input maybe used as an output and vice-versa. Also these switches contain linearization circuitry which lowers the on resis-tance and increases switch linearity. These devices allow control of up to -6V (peak) analog signals with digital con-trol signals of 0 to 6V. Three supply pins are provided for VCC, ground, and V EE. This enables the connection of 0- 5V logic signals when VCC = 5V and an analog input range of -5V when V EE = 5V. All three devices also have an inhibit control which when HIGH will disable all switches to their off state. All analog inputs and outputs and digital inputs are protected from electrostatic damage by diodes to V CC and ground. MM74HC4051: This device connects together the outputs of 8 switches, thus achieving an 8 channel Multiplexer. The binary code placed on the A, B, and C select lines deter-mines which one of the eight switches is "on", and connects one of the eight inputs to the common output. MM74HC4052: This device connects together the outputs of 4 switches in two sets, thus achieving a pair of 4-channel multiplexers. The binary code placed on the A, and Bselect lines determine which switch in each 4 channel section is "on", connecting one of the four inputs in each sec-tion to its common output. This enables the implementation of a 4-channel differential multiplexer. MM74HC4053: This device contains 6 switches whose out-puts are connected together in pairs, thus implementing a triple 2 channel multiplexer, or the equivalent of 3 single-pole-double throw configurations. Each of the A, B, or C select lines independently controls one pair of switches,selecting one of the two switches to be "on".
