MC14053BDG

MC14053BDG Description

The MC14053BDG from onsemi is a high-performance triple SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in mixed-signal applications. Housed in a 16-SOIC package, this IC integrates three independent switches with low on-state resistance (280Ω max) and minimal leakage current (100nA max), ensuring efficient signal integrity. It operates across a wide voltage range (3V to 18V), making it versatile for both low-voltage and industrial-level designs. With a -3dB bandwidth of 17MHz, it supports moderate-frequency analog signals, while its low channel capacitance (7.5pF) minimizes crosstalk and distortion.
