Description

CD4051BMS, CD4052BMS and CD4053BMS analog multiplexers/demultiplexers are digitally controlled analog switches having low ON impedance and very low OFF leakage current. Control of analog signals to 20V peak-topeak can be achieved by digital signal amplitudes to 20V (if VDD-VSS 3V, a VDD-VEE to 13V can be controlled; for VDD-VEE level differences above 13V, a VDDVSS of at least 4.5V is required). For example, if VDD = +4.5V, VSS = 0, and VEE = -13.5V, analog signals from to +4.5V can be controlled by digital inputs to 5V. These multiplexer circuits dissipate extremely low quiescent power over the full VDD-VSS and VDD-VEE supply voltage ranges, independent of the logic state of the control signals. When a logic "1" is present at the inhibit input terminal all channels are off. The is a single 8 channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select of 8 channels to be turned on, and connect one of the 8 inputs to the output. The is a differential 4 channel multiplexer having two binary control inputs, A and B, and an inhibit input. The two binary input signals select of 4 pairs of channels to be turned on and connect the analog inputs to the outputs. The is a triple 2 channel multiplexer having three separate digital control inputs, A, B, and C, and an inhibit input. Each control input selects one of a pair of channels which are connected in a single pole double-throw configuration. The CD4051BMS, CD4052BMS and CD4053BMS are supplied in these 16 lead outline packages: Braze Seal DIP Frit Seal DIP Ceramic Flatpack *CD4051B Only CD4052B, CD4053 Only H4T

Applications
Analog and Digital Multiplexing and Demultiplexing A/D and D/A Conversion Signal Gating

* When these devices are used as demultiplexers the "CHANNEL IN/OUT" terminals are the outputs and the "COMMON OUT/IN" terminals are the inputs.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 321-724-7143 | Copyright � Intersil Corporation 1999
