MC14051BDTR2

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14051BDTR2 is a digitally controlled analog switch implementing an SP8T solid state switch within a 16-pin TSSOP package. It operates on a single supply voltage ranging from 3.0 Vdc to 18 Vdc, with the analog signal range spanning the complete supply voltage difference between VDD and VEE. The device features low ON impedance and very low OFF leakage current, ensuring efficient signal routing. Key electrical parameters include a maximum ON resistance of 280 ohms at 15 V supply, a channel-to-channel matching of 10 ohms, and a -3dB bandwidth of 17 MHz. The component supports an operating temperature range from -55°C to +125°C.
