Additional preview pages of the HD74ALVCH16500 datasheet.

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

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 ±24 mA (@V CC = 3.0 V).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors HD74ALVCH16500 Function Table.
