Description
The HD74LVC74 has independent data, preset, clear, and clock inputs Q and
Q
outputs in a 14 pin package. The logic
level present at the data input is transferred to the output during the positive going transition of the clock pulse. Preset
and clear are independent of the clock and accomplished by a low level at the appropriate input. 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.
