HD74LVC574A

Octal D-type Flip Flops with 3-state Outputs

ADE-205-117B(Z)

3rd Edition

December 1996

Description

The HD74LVC574A has eight edge trigger D type flip flops with three state outputs in a 20 pin package.

Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going

transitions of the clock input. When the clock input goes low, data at the D inputs will be retained at the

outputs until clock input returns high again. When a high logic level is applied to the output control input,

all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the

state of the storage elements. Low voltage and high speed operation is suitable at the battery drive product

(note type personal computer) and low power consumption extends the life of a battery for long time

operation.
