TECHNICAL DATA
Octal 3-State
Inverting D Flip-Flop
High-Performance Silicon-Gate CMOS
IN74HC534A
The IN74HC534A is identical in pinout to the LS/ALS534. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL 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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
