Description

These 18-bit universal bus transceivers of CY74FCT162500T can be operated in transparent, latched, or clock modes by combining D-type latches and D-type flip-flops. Data flow in each direction is controlled by output-enable (OEAB and OEBA ), latch enable (LEAB and LEBA), and clock inputs ( CLKBA andCLKBA) inputs. For A-to-B data flow, the CY74FCT162500T operates in transparent mode when LEAB is HIGH. When LEAB is LOW, the A data is latched if CLKAB is held at a HIGH or LOWlogic level. If LEAB is LOW, the A bus data is stored in the latch/flip-flop on the HIGH-to-LOWtransition of CLKBA. OEAB performs the output of CY74FCT162500T enable function on the B port. Data flow from B-to-A is similar to that of A-to-B and is controlled by OEAB and OEBA , LEBA, and CLKBA. The output buffers are designed with power-off disable feature that allows live insertion of boards.

The CY74FCT16500T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162500T has 24-mA balanced output drivers with current limiting resistors in the outputs. CY74FCT162500T reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce.

The CY74FCT162500T is ideal for driving transmission lines.
