TI CD74LPT16501AMT

The CD74LPT16501 is an 18-bit registered bus transceiver featuring D-type latches and flip-flops, allowing data to flow in transparent, latched, and clocked modes. Output enables (OEAB and OEBA), latch enables (LEAB and LEBA), and clock (CLKAB and CLKBA) inputs control data flow in each direction. When LEAB is HIGH, the device operates in transparent mode for A-to-B data flow. When LEAB is LOW, A data is latched if CLKAB is held at a HIGH or LOW logic level. If LEAB is LOW, A bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CLKAB. OEAB performs the output enable function at port B. Using OEBA, LEBA, and CLKBA, data flow from port B to port A operates similarly. This high-speed, low-power device features a feed-through architecture for easy board layout. The CD74LPT16501 can be driven by 3.3V or 5.0V devices, allowing it to serve as a translator in mixed 3.3V/5.0V systems.
