MC74HC74A 数据手册

High–Performance Silicon–Gate CMOS

The MC74HC74A is identical in pinout to the LS74. The device

inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

This device consists of two D flip–flops with individual Set, Reset,

and Clock inputs. Information at a D–input is transferred to the

corresponding Q output on the next positive going edge of the clock

input. Both Q and Q outputs are available from each flip–flop. The Set

and Reset inputs are asynchronous.

*Both outputs will remain high as long as Set and Reset are low, but the output

states are unpredictable if Set and Reset go high simultaneously.
