The HCF4053B is a low-on impedance, low-off leakage current, digitally controlled analog switch that can be used for multiplexing and demultiplexing. It has a low static current, high linearity and wide voltage range.
The HCF4053B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages. It functions as a digitally controlled analog switch with low ON impedance and very low OFF leakage current, dissipating extremely low quiescent power independent of logic states.
The device is a triple 2-channel multiplexer with three separate digital control inputs (A, B, and C) and an inhibit input. Each control input selects one of a pair of channels connected in a single pole double-throw configuration. It supports a wide range of digital and analog signal levels, with digital inputs from 3 to 20V and analog signals up to 20V peak-to-peak.
| On Resistance (Typical) | 1252 Ohms |
|---|---|
