Functional Description
These 18-bit universal bus transceivers 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 (CLKAB and CLKBA)
inputs. For A-to-B data flow, the device 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 LOW logic level. If LEAB
is LOW, the A bus data is stored in the latch/flip-flop on the
HIGH-to-LOW transition of CLKAB. OEAB performs the output
enable function on the B port. Data flow from B-to-A is similar
to that of A-to-B and is controlled by OEBA, LEBA, and
CLKBA. The output buffers are designed with power-off
disable feature that allows live insertion of boards.
The
CY74FCT16500T
is
high-capacitance loads and low-impedance backplanes.
The CY74FCT162500T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for
minimal undershoot and reduced ground bounce. The
CY74FCT162500T is ideal for driving transmission lines.
