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 A; 0.1 A @ 25C
Outputs Source/Sink 24 mA

This device contains protection circuitry to guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of any voltage
higher than maximum rated voltages to this high-impedance circuit. For proper operation, V
IN
and
V
OUT
should be constrained to the range GND
(V
IN
or V
OUT
)
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or
V
CC
). Unused outputs must be left open.
