onsemi 74HC574
The 74HC574 is identical in pinout to the LS574. The device inputs are compatible with standard CMOS outputs; with pull−up resistors, they are compatible with LSTTL outputs. 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.| Part No. | 74HC574 |
