KK4051B

TECHNICAL DATA KK4051B Analog Multiplexer Demultiplexer High-Performance Silicon-Gate CMOS The KK4051B 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 KK4051B 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 SUF FIX PL AST IC 16 1 16 1 D SUFFI X S O IC ORDERING INFORMATION KK4051BN Plastic DIP KK4051BD 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 ANALO G INPUTS/OUTPUTS X4 X5 13 14 15 12 1 5 MULTIPLEXER/ DEMULTIPLEXER 3 X COMMON OUTPUT/INPUT Control Inputs Enable C L L L L L L PIN 16 =VCC PIN 7 = VEE PIN 8 = GND L L L L L L H H H H Select B L L H H L L H H X A L H L H L H L H X ON Channels X0 X1 X2 X3 X4 X5 X6 X7 None X6 2 X7 4 A CHANNEL-SELECT B INPUTS C ENABLE 11 10 9 6 H X H = high level L = low level X = don’t care 1 KK4051B MAXIMUM RATINGS* Symbol VCC VIN IIN PD Ptot Tstg TL Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Input Current, per Pin Power Dissipation in Still Air Power Dissipation per Output Transistor Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SO Package) Value -0.5 to +20 -0.5 to VCC +0.5 ±10 500*1 100 -65 to +150 260 Unit V V mA mW mW °C °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. 2 KK4051B DC ELECTRICAL CHARACTERISTICS Digital Section VCC Symbol VIH Parameter Minimum High-Level Input Voltage, Channel-Select or Enable Inputs Maximum Low -Level Input Voltage, Channel-Select or Enable Inputs Maximum Input Leakage Current, Channel-Select or Enable Inputs Maximum Quiescent Supply Current (per Package) Test Conditions VIS=VCC thru 1kΩ VEE=GND=0 IIS
