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). 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
LOW-to-HIGH 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 a power-off disable
feature to allow live insertion of boards.
The
CY74FCT16501T
is
high-capacitance loads and low-impedance backplanes.
THE CY74FCT162501T 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
CY74FCT162501T is ideal for driving transmission lines.
The CY74FCT162H501T is a 24-mA balanced output part, that
has “bus hold” on the data inputs. The device retains the input’s
last state whenever the input goes to high impedance. This
eliminates the need for pull-up/down resistors and prevents
floating inputs.
