MC74AC74, MC74ACT74

Dual D−Type Positive

Edge−Triggered Flip−Flop

The MC74AC74/74ACT74 is a dual D−type flip−flop with

Asynchronous Clear and Set inputs and complementary (Q,Q)

outputs. Information at the input is transferred to the outputs on the

positive edge of the clock pulse. Clock triggering occurs at a voltage

level of the clock pulse and is not directly related to the transition time

of the positive-going pulse. After the Clock Pulse input threshold

voltage has been passed, the Data input is locked out and information

present will not be transferred to the outputs until the next rising edge

of the Clock Pulse input.

PDIP−14

N SUFFIX

CASE 646

Asynchronous Inputs:

SOIC−14

D SUFFIX

CASE 751A

LOW input to S (Set) sets Q to HIGH level

LOW input to C (Clear) sets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C and S makes both Q and Q HIGH

TSSOP−14

Features

• Outputs Source/Sink 24 mA

• ′ACT74 Has TTL Compatible Inputs
