Description

The RD74LVC573B has eight D type latches with three state outputs in a 20-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, 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.
