54FCT574ATDB

Overview

The 54FCT574ATDB is an octal D-type flip-flop manufactured by Renesas Electronics Corporation, belonging to the FCT logic series. It features a single circuit with eight bits per element and utilizes a 20-CDIP package for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -55°C to +125°C. Key electrical specifications include a propagation delay of 6.5 ns and a maximum delay of 7.2 ns at 50 pF load capacitance. Output drive capabilities are defined by a low-level output current of 48 mA and a high-level output current of -15 mA, with static current consumption of 1 mA.
