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.
