Description
General part information
74HC574 Series
High-Performance Silicon-Gate CMOSThe MC74HC574A is identical in pinout to the LS574. 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, all device outputs are forced to the high-impedance state. Thus, data may be stored even when the outputs are not enabled.The HC574A 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.
