AS-6408 Analog Digital Multiplexer Switch

Features

 

    Wide Range of Digital and Analog Signal Levels
        Digital:3V to 20V
        Analog:≤20VP-P
    Low ON Resistance, 125Ω (Typ) Over 15VP-P Signal Input Range for VDD-VEE = 18V
    High OFF Resistance, Channel Leakage of ±100pA (Typ) at VDD-VEE = 18V
    Matched Switch Characteristics, rON = 5Ω (Typ) for VDD-VEE = 15V
    Very Low Quiescent Power Dissipation Under All Digital-Control Input and Supply Conditions, 0.2μW (Typ) at VDD-VSS = VDD-VEE = 10V
    Binary Address Decoding on Chip
    5V, 10V, and 15V Parametric Ratings
    Maximum Input Current of 1μA at 18V Over Full Package Temperature Range, 100nA at 18V and 25oC
    Break-Before-Make Switching Eliminates Channel Overlap
    One 8CH output and one 1CH output
    Onboard UNO CORE ( *OPTION* ), can be working alone with UART output

 

Typical Application

 

    AS-6408 have two output ways, one is 64CH <-> 8CH and one is 64 <-> 1CH, the 1CH output is after the 8CH output and they can working at the same time.
    AS-6408 have onboard UNO CORE design , that means it can be working alone to process the 64CH input and read by A0 to A7 with 10bit ADC , and then sent data via TXD/RXD , if you using the RF UNO CORE it can be implement wireless data acquisition very easy.
The input signal level should not exceed VCC (Range of 0 to VCC), otherwise it may cause signal distortion.
    The control signal is standard COMS TTL-3.3V level. 
    Main IC using 74HC4051D from NXP , the datasheet link : http://www.nxp.com/products/automotive-products/discrete-and-logic/logic/analog-switches/8-channel-analog-multiplexer-demultiplexer:74HC4051D-Q100?fsrch=1&sr=3&pageNum=1
