It switches one of four input lines to a single output — a 1 x 4:4 configuration — operating from a 3 V to 3.6 V rail. The output drive is rated at 2 mA high and low, suited for CMOS logic-level fan-out rather than high-current buses. ## Temperature grade and deployment context Rated for 0°C to 70°C, this is a commercial-temperature part. ## Lifecycle and sourcing posture It remains a current-production part, available through the standard independent-distribution channel.","metaTitle":"PCA8550D Multiplexer, 1 x 4:4, 16-SOIC, 3V-3.6V","metaDescription":"PCA8550D is an active 4-line multiplexer in a 16-SOIC package.
