TECHNICAL DATA
IN74AC534
Octal 3-State
Inverting D Flip-Flop
High-Speed Silicon-Gate CMOS
The IN74AC534 is identical in pinout to the LS/ALS534,
HC/HCT534. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS outputs.
Data meeting the setup time is clocked, in inverted form, 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.
