RD74LVC573B Octal D-type Transparent Latches with 3-state Outputs REJ03D0209–0100Z Rev.1.00 Apr.15.2004 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.
