1 / 17 page April 2008 Rev 4 1/17 17 M74HC4051 Single 8-channel analog multiplexer/demultiplexer Features ■ Low power dissipation: –ICC = 4 μA(max) at TA=25°C ■ Logic level translation to enable 5 V logic signal to communicate with ± 5 V analog signal ■ Low ON resistance: 70 Ω typ (VCC - VEE = 4.5 V) 50 Ω typ (VCC - VEE = 9 V) ■ Wide analog input voltage range : ± 6V ■ Fast switching: tpd = 15 ns (typ) at TA = 25 °C ■ Low crosstalk between switches ■ High ON/OFF output voltage ratio ■ Wide operating supply voltage range (VCC - VEE) = 2 to 12 V ■ Low sine wave distortion: 0.02% at VCC - VEE = 9 V ■ High noise immunity: VNIH = VNIL = 28 % VCC (min) ■ Pin and function compatible with 74 series 4051 Description The M74HC4051 is a single 8-channel analog multiplexer/demultiplexer fabricated with silicon gate C2MOS technology, pin-to-pin compatible with the equivalent metal gate CMOS4000B series. It contains 8 bidirectional and digitally controlled analog switches. A built-in level shifting is included to allow an input range up to ± 6 V (peak) for an analog signal with digital control signal of 0 to 6 V. The VEE supply pin is provided for analog input signals. It has an inhibit (INH) input terminal to disable all the switches when is at high level. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND. A, B and C control inputs select one channel out of eight. All inputs are equipped with protection circuits against static discharge and transient excess voltage. PDIP-16 SOP-16 TSSOP-16 Table 1.
