Description
The RD74LVC16373B 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.
