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 : ± 6 V 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 TSSOP-16 PDIP-16 SOP-16 ■ ■ ■ ■ ■ ■ ■ ■ 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. Table 1.
