TECHNICAL DATA
IN74ACT534
Octal 3-State
Inverting D Flip-Flop
High-Speed Silicon-Gate CMOS
The IN74ACT534 is identical in pinout to the LS/ALS534,
HC/HCT534. The IN74ACT534 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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.
