Overview: DATA SHEET .onsemi. Octal 3-State Non-Inverting D Flip-Flop
High−Performance Silicon−Gate CMOS
MC74HC374A, MC74HCT374A
The MC74HC374A/MC74HCT374A is identical in pinout to the LS374. The MC74HC374A inputs are patible with standard CMOS outputs; with pull−up resistors, they are patible with LSTTL outputs. The MC74HCT374A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
Data meeting the set−up 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 HC374A/HCT374A is identical in function to the HC574A/HCT574A which has the input pins on the opposite side of the package from the output. This device is similar in function to the HC534A/HCT534A which has inverting outputs.
