System Logic

Semiconductor

SLS

Octal 3-State Inverting D Flip-Flop

High-Performance Silicon-Gate CMOS

The SL74HC534 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
