MC74HCT374AN Octal 3-State Noninverting D Flip-Flop with LSTTL-Compatible Inputs (High-Performance Silicon-Gate CMOS)
Description:
The MC54/74HCT374A may be used as a level converter for
interfacing TTL or NMOS outputs to High–Speed CMOS inputs.
The HCT374A is identical in pinout to the LS374.
Data meeting the setup and hold time is clocked to the outputs with the
rising edge of Clock. The Output Enable does not affect the state 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 HCT374A is identical in function to the HCT574A, which has the
input pins on the opposite side of the package from the output pins. This
device is similar in function to the HCT534A, which has inverting outputs.
