General Description

The LCX16501 is an 18-bit universal bus transceiver combining 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 LCX16501 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment.

The LCX16501 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power.
