74ALVC16501 datasheet



The 74ALVC16501 is an 18-bit universal bus transceiver which combines D-type latches and D-type flip-flops to allow data flow in transparent, latched, and clocked modes.

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. If LEAB is LOW, the A
bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CLKAB. When OEAB is HIGH, the outputs are active. When OEAB is LOW, the outputs are in a highimpedance state.
