74LS399 IC - (SMD Package) - Quad 2-Port Register IC (74399 IC)

The 74LS399 are Quad 2-Port Registers. They are the logical equivalent of a quad 2-input multiplexer followed by a quad 4-bit edge-triggered register. A Common Select input selects between two 4-bit in put ports (data sources). The selected data is transferred to the output register on the LOW-to-HIGH transition of the Clock input. The 74LS398 features Q and Q inputs, while the 74LS399 has only Q outputs.
