These 18-bit universal bus transceivers combine 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. The LCX16500 is designed for low voltage (2.5V or 3.3V) VCC applications with the capability of interfacing to a 5V signal environment. The LCX16500 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power.
