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.

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. _C 260 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. †Derating — Plastic DIP: – 10 mW/_C from 65_ to 125_C SOIC Package: – 7 mW/_C from 65_ to 125_C TSSOP Package: − 6.1 mW/_C from 65_ to 125_C For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor High−Speed CMOS Data Book (DL129/D).
