HD74ALVCH162500 Datasheet (Hitachi Semiconductor) - 18-bit Universal Bus Transceivers with 3-state Outputs

HD74ALVCH162500, 18-bit Universal Bus Transceivers with 3-state Outputs

Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock ( CLKAB and CLKBA) inputs.

For A to B data flow, the device operates in the transparent mode when LEAB is high.

When LEAB is low, the A data is latched if CLKAB is held at a high or lo
