The IN74HCT574A is identical in pinout to the LS/ALS574. This device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs.
Data meeting the setup time of the IN74HCT574A 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- mpedance state; thus, data may be stored even when the outputs are not enabled.
