onsemi Logic - Logic - Flip Flops - MM74HCT574SJ MM74HCT574SJ

The MM74HCT574SJ is an octal D-type flip-flop designed using advanced silicon-gate CMOS technology, offering low power consumption and compatibility with LS-TTL input and output characteristics. It features positive edge triggering, allowing data at the D inputs to be transferred to the Q outputs on the rising edge of the clock input, provided that setup and hold time requirements are met. The device includes 3-state outputs capable of driving up to 15 LS-TTL loads, making it suitable for bus-oriented systems. This flip-flop operates within a supply voltage range of 4.5V to 5.5V and has a typical propagation delay of 17 ns. It is designed to interface between TTL and NMOS components as well as standard CMOS devices, and it can serve as a plug-in replacement for LS-TTL devices, potentially reducing power consumption in existing designs. The MM74HCT574SJ is also protected against static discharge, ensuring reliability in various applications.
