MC74HC74A D

MC74HC74A
Dual D Flip-Flop with Set
and Reset
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.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.
