CD4051BE - IC 8: 1 analog multiplexer / demultiplexer, single , 240 ohm, 3V / 20V, DIP-16
The CD4051BE analog multiplexer is a digitally controlled analog switch with low impedance in ON and very low leakage current in OFF. The control of analog signals up to 20VP-P can be obtained through digital signals of amplitude from 4.5V to 20V (if VDD-VSS = 3V, VDD-VEE can be controlled up to 13V; for differences in VDD-VEE level above 13V, a VDD-VSS of at least 4.5V is required). For example, if VDD = + 4.5V, VSS = 0V and VEE = -13.5V, analog signals from -13.5V to + 4.5V can be controlled with digital inputs from 0V to 5V. These circuits dissipate extremely low rest energy over the entire supply voltage ranges VDD-VSS and VDD-VEE, regardless of the logic state of the control signals. When a logic 1 is present in the input inhibit terminal, all channels are deactivated. CD4051BE has three binary control inputs, A, B and C, and an inhibit input. The three binary signals select from 1 to 8 cana
Â
- Wide range of levels of digital and analog signals
- Low resistance in ON, 125 Ohm typical on a 15VP-P signal input range for VDD-VEE = 18V
- High resistance in OFF, channel dispersion of  ± 100pA typical with VDD-VEE = 18V
- Logic level conversion
- Matched switch features, rON = 5 typical for VDD-VEE = 15V
- Very low power dissipation at rest in all power supply and digital control input conditions
- Decoding of the binary address on chip
- Parametric values ??of 5V, 10V and 15V
- Tested at 10% for the quiescent current at 20V
- Maximum input current of 1µA with 18V over the complete temperature range; 100nA with 18V and 25 ° C
- Break-before-make switching eliminates channel overlap
