The CY74FCT399T is a high-speed quad 2-input register that selects four bits of data from either of two sources (ports) under control of a common select (S) input. Selected data are transferred to a 4-bit output register synchronous with the low-to-high transition of the clock (CP) input. The 4-bit • Function, Pinout, and Drive Compatible With FCT and F Logic\n• Edge-Rate Control Circuitry for Significantly Improved Noise Characteristics\n• Matched Rise and Fall Times\n• 200-V Machine Model (A115-A)\n• Fully Compatible With TTL Input and Output Logic Levels\n• 64-mA Output Sink Current 32-mA O;
