ON MC74HCT574ADWR2G Octal 3-state noninverting d flip-flop with lsttl-compatible input Datasheet

MC74HCT574A
Octal 3-State Noninverting
D Flip-Flop with
LSTTL-Compatible Inputs
High−Performance Silicon−Gate CMOS
http://onsemi.com
The MC74HCT574A is identical in pinout to the LS574. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High Speed CMOS inputs.
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, all device outputs
are forced to the high−impedance state. Thus, data may be stored even
when the outputs are not enabled.
The HCT574A is identical in function to the HCT374A but has the
flip−flop inputs on the opposite side of the package from the outputs to
facilitate PC board layout.

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.
