1 MICOM DATA MM74HC4051 8-CHANNEL ANALOG MULTIPLEXER GENERAL DESCRIPTION The MM74HC4051, MM74HC4052 and MM74HC4053 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 circuity which lowers the on resistance and increases switch linearity. These devices allow control of up to ± 6V(peak) analog signals with digital control signals of 0 to 6V. Three supply pins are provided for V CC, ground, and V EE. This enables the connection of 0-5V logic signals when V CC = 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. 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. FEATURES - Wide analog input voltage range: ±6V - Low on resistance: 50 typ.(V CC-V EE = 4.5V), 30 typ.(V CC-V EE = 9V) - Logic level translation to enable 5V logic with ± 5V analog signals - Low quiescent current: 80µA maximum (74HC) - Matched Switch characteristic ORDERING CODE: Devices also available in Tape and Reel. Specify by appending the suffix letter Xto the ordering code.
