Description

The SEEIC1002 is an improved high precision analog multiplexer designed for electronic components. It is available in two models: PS398 and PS399. The PS398 is an 8-channel single-ended mux, while the PS399 is a 4-channel differential multiplexer. Both models provide precise selection of inputs to a common output based on address pins. They also feature an enable pin for disabling all switches, making them convenient for stacking multiple devices.
