Description
Octal D-type Flip Flops With 3-state Outputs - Hitachi Semiconductor
Manufacturer
Renesas Electronics Corporation.
Datasheet
Description
The HD74LVC534 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 reguirements, are transferred to the Q outputs on positive going
transitions of the clock input. When the latch enable goes low, data at the D inputs will be retained at the
outputs until latch enable 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.
