DM74LS534

Octal D-Type Flip-Flop with 3-STATE Outputs

General Description

The DM74LS534 is a high speed, low power octal D-type

flip-flop featuring separate D-type inputs for each flip-flop

and 3-STATE outputs for bus oriented applications. A buff-

ered Clock (CP) and Output Enable (OE) is common to all

flip-flops. The DM74LS534 is the same as the DM74LS374

except that the outputs are inverted.
