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
