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. TTL/NMOS Compatible Input Levels Outputs Directly Interface to
CMOS, NMOS, and TTL Operating
Voltage Range: 4.5 to 5.5 V Low Input Current: 1.0 µA; 0.1 µA @ 25°C Outputs Source/Sink 24 mA
