Description
The HD74LVC16374A 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.
