HD74HCT373/HD74HCT533
Octal D-type Transparent Latches (with 3-state outputs)/
Octal D-type Transparent Latches (with inverted 3-state outputs)
Description
When the latch enable input is high, the Q outputs of HD74HCT373 will follow the D inputs and the Q
outputs of HD74HCT533 will follow the inversion of 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
present at the other inputs and the state of the storage elements.
