RD74LVC373B
Octal D-type Transparent Latches with 3-state Outputs
REJ03D0381–0100
Rev.1.00
Nov. 26, 2004
Description
The RD74LVC373B 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 battery for long time operation.
