MM74HC574
3-State Octal D-Type Edge-Triggered Flip-Flop
The MM74HC574 high speed octal D−type flip−flops utilize advanced silicon−gate P−well CMOS technology. They possess the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS−TTL loads. Due to the large output drive capability and the 3−STATE feature, these devices are ideally suited for interfacing with bus lines in a bus organized system.
These devices are positive edge triggered flip−flops. Data at the D inputs, meeting the set−up and hold time requirements, are transferred to the Q outputs on positive going transitions of the CLOCK (CK) input.
