RD74LVC574B
Octal D-type Flip Flops with 3-state Outputs
REJ03D0210–0100Z
Rev.1.00
Apr.15.2004
Description
The RD74LVC574B 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.
