Functional Description
These
low-power devices. 16-bit operation is achieved by connecting
the control lines of the two 8-bit registered transceivers
together. For data flow from bus A-to-B, CEAB must be LOW
to allow data to be stored when CLKAB transitions from
LOW-to-HIGH. The stored data will be present on the output
when OEAB is LOW. Control of data from B-to-A is similar and
is controlled by using the CEBA, CLKBA, and OEBA inputs.
The output buffers are designed with a power-off disable
feature to allow for live insertion of boards.
The
CY74FCT16952T
is
high-capacitance loads and low-impedance backplanes.
The CY74FCT162952T 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
CY74FCT162952T is ideal for driving transmission lines.
The CY74FCT162H952T 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.
