HD74ALVCH162835 Datasheet (Hitachi Semiconductor) - 18-bit Universal Bus Drivers with 3-state Outputs

HD74ALVCH162835, 18-bit Universal Bus Drivers with 3-state Outputs

Data flow from A to Y is controlled by the output enable (OE ).

The device operates in the transparent mode when LE is high.

The A data is latched if CLK is held at a high or low logic level.

If LE is low, the A bus data is stored in the latch flip flop on the low to high transition of CLK.
