Description
The HD74LVC16373A has sixteen D type latches with three state outputs in a 48 pin package. When the latch enable
input is high, the Q outputs will follow the D inputs. 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 (1G, 2G), 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.
