74ALVC16500 - Low Voltage 18-Bit Universal Bus Transceivers

General Description

The ALVC16500 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.

74ALVC16500 Low Voltage 18-Bit Universal Bus Transceivers with 3.6V Tolerant Inputs and Outputs October 2001 Revised October 2001 74ALVC16500 Low Voltage 18-Bit Universal Bus Transceivers with 3.6V Tolerant Inputs and Outputs General Description The ALVC16500 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.
