Overview
The HMC253ALC4TR is a non-reflective Single-Pole Eight-Throw (SP8T) switch manufactured by Analog Devices Inc. This component is housed in a leadless, RoHS compliant 4x4 mm ceramic Surface Mount Technology (SMT) package. It features wideband operation from DC to 3.5 GHz, making it suitable for a variety of high-frequency applications. The switch operates with a single positive bias and is compatible with TTL/CMOS control signals, requiring only 3 control lines and a +5V supply to select each path.
