HD74LVC16373A
HD74LVC16373A is 16-bit D-type Transparent Latches with 3-state Outputs manufactured by Hitachi Semiconductor.
Description
The HD74LVC16373A 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 (1 G, 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 puter) and low power consumption extends the life of a battery for long time operation.
