MM74HCT573 • MM74HCT574 Octal D-Type Latch • 3-STATE Octal D-Type Flip-Flop February 1990 Revised May 2005 MM74HCT573 • MM74HCT574 Octal D-Type Latch • 3-STATE Octal D-Type Flip-Flop General Description The MM74HCT573 octal D-type latches and MM74HCT574 octal D-type flip-flop advanced silicon-gate CMOS technology, which provides the inherent benefits of low power consumption and wide power supply range, but are LS-TTL input and output characteristic and pin-out compatible. The 3-STATE outputs are capable of driving 15 LS-TTL loads. All inputs are protected from damage due to static discharge by internal diodes to VCC and ground. When the MM74HCT573 Latch Enable input is HIGH, the Q outputs will follow the D inputs.
