TECHNICAL DATA IW4051B Analog Multiplexer Demultiplexer High-Performance Silicon-Gate CMOS The IW4051B analog multiplexer/demultiplexer is digitally controlled analog switches having low ON impedance and very low OFF leakage current. Control of analog signals up to 20V peak-to-peak can be achieved by digital signal amplitudes of 4.5 to 20V (if VCC - GND = 3V, a VCC - VEE of up to 13 V can be controlled; for VCC-VEE level differences above 13V a VCC - GND of at least 4.5V is required). These multiplexer circuits dissipate extremely low quiescent power over the full VCC -GND and VCC - VEE supply-voltage ranges, independent of the logic state of the control signals. When a logic “1”is present at the ENABLE input terminal all channels are off. The IW4051B is a single 8-channel multiplexer having three binary control inputs, A, B and C, and an ENABLE input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. • Operating Voltage Range: 3.0 to 18 V • Maximum input current of 1 μA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C • Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply N SUFFIX PLASTIC 16 1 D SUFFIX SOIC 16 1 ORDERING INFORMATION IW4051BN Plastic DIP IW4051BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM Single-Pole, 8-Position Plus Common Off FUNCTION TABLE X0 X1 X2 X3 ANALOG INPUTS/OUTPUTS X4 X5 13 14 Control Inputs 15 1 MULTIPLEXER/ DEMULTIPLEXER A CHANNEL-SELECT B INPUTS C ENABLE 3 X COMMON OUTPUT/INPUT Select Channels C B A L L L L X0 L L L H X1 L L H L X2 L L H H X3 L H L L X4 L H L H X5 PIN 16 =VCC L H H L X6 PIN 7 = VEE L H H H X7 H X H = high level L = low level X = don’t care X X None 5 X6 2 X7 Enable 12 ON 4 11 10 9 6 PIN 8 = GND Rev. 00 IW4051B MAXIMUM RATINGS* Symbol Parameter VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) IIN DC Input Current, per Pin PD Power Dissipation in Still Air Ptot Power Dissipation per Output Transistor Tstg Storage Temperature TL Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SO Package) Value Unit -0.5 to +20 V -0.5 to VCC +0.5 V ±10 mA 500*1 mW 100 mW -65 to +150 °C 260 °C *Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused digital pins must be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused Analog I/O pins may be left open or terminated.
