MC74HCT74A

Dual D Flip−Flop with Set

and Reset with LSTTL

Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT74A is identical in pinout to the LS74. This device

may be used as a level converter for interfacing TTL or NMOS outputs

to High Speed CMOS inputs.

MARKING

DIAGRAMS

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 unpredict-

able if Set and Reset go high simultaneously.
