RD74LVC16374B
16-bit D-type Flip Flops with 3-state Outputs
REJ03D0501–0100
Rev.1.00
Jan. 24, 2005
Description
The RD74LVC16374B has sixteen edge trigger D type flip flops with three state outputs in a 48 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 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.
