CY74FCT399CTS0C Quad 2-Input Register For Data Selection

CY74FCT399CTS0C is a quad 2-input register used to select four bits from either of two sources and capture them into an output register on a clock edge. It’s useful for bus multiplexing, staged handoff between blocks, and cleaning up control signals before they enter a synchronous domain. The device documentation describes edge-triggered D-type output registers and a common select input that routes the chosen data set. Use CY74FCT399CTS0C where you need deterministic selection plus registered outputs to reduce hazards and simplify timing closure. Request a quote for CY74FCT399CTS0C.
