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 low logic level.

VCC = 2.3 V to 3.6 V.
Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
High output current ±12 mA (@VCC = 3.0 V).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162500 Function Table.
