Description

This is 8-channel analog multiplexer/demultiplexer. 74HC4051; 74HCT4051 8-channel analog multiplexer, demultiplexer Rev. 8 5 February 2016 Product data sheet 1. General description The 74HC4051; 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer, demultiplexer applications. The switch features three digital select inputs (S0, S1 and S2), eight independent inputs, outputs (Yn), a common input, output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits Wide analog input voltage range from 5 V to +5 V Complies with JEDEC standard no. 7A Low ON resistance: 80 (typical) at VCC VEE = 4.5 V 70 (typical) at VCC VEE = 6.0 V 60 (typical) at VCC VEE = 9.0 V Logic level translation: to enable 5 V logic to communicate with 5 V analog signals Typical ‘break before make’ bu.
