The MC74HCT374A may be used as a level converter for interfacing TTL or NMOS outputs to HighSpeed 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 flipflops, but when Output Enable is high, the outputs are forced to the highimpedance 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.
