Description
Fairchild Semiconductor 74VHC4053M IC Multiplexer / Demultiplexer 3 x 2:1 Surface Mount / SMD 16-SOIC (0.154″, 3.90mm Width)
These multiplexers 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 may be used as an output and vice-versa. Also these switches contain linearization circuitry which lowers the “on” resistance and increases switch linearity. These devices allow control to ±6V (peak) analog signals with digital control signals to 6V. Three supply pins are provided for VCC, ground, and VEE. This enables the connection of 05V logic signals when VCC = 5V and an analog input range of ±5V when VEE = 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 VCC and ground. VHC4051: 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 determines which one of the eight switches is “on”, and connects one of the eight inputs to the common output. VHC4052: 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 B select lines determine which switch in each 4 channel section is “on”, connecting one of the four inputs in each section to its common output. This enables the implementation a 4-channel differential multiplexer. VHC4053: This device contains 6 switches whose outputs are connected together in pairs, thus implementing a triple 2 channel multiplexer, or the equivalent of 3 single-poledouble throw configurations. Each of the or C select lines independently controls one pair of switches, selecting one of the two switches to be “on”.
