•The BCT4223 is a high-performance, dual single-pole double-throw (SPDT) analog switch. Specified over a wide operating power supply range, 1.65V to 5.0V. Targeted applications include battery powered equipment that benefit from ultra low ON-resistance(0.4Ω) and fast switching speeds.Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.
