MC74HC374A
Octal 3-State Non-Inverting
D Flip-Flop
High−Performance Silicon−Gate CMOS
The MC74HC374A is identical in pinout to the LS374. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
Data meeting the setup time is clocked to the outputs with the rising
edge of the clock. The Output Enable input does not affect the states of
the flip−flops, but when Output Enable is high, the outputs are forced
to the high−impedance state; thus, data may be stored even when the
outputs are not enabled.
The HC374A is identical in function to the HC574A which has the
input pins on the opposite side of the package from the output. This
device is similar in function to the HC534A which has inverting
outputs.

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.
