Functional Description
These 16-bit transceivers are designed for use in bidirectional
synchronous communication between two buses, where high
speed and low power are required. With the exception of the
CY74FCT16245T, these devices can be operated either as
two independent octals or a single 16-bit transceiver. Direction
of data flow is controlled by (DIR), the Output Enable (OE)
transfers data when LOW and isolates the buses when HIGH.
The output buffers are designed with power off disable capa-
bility to allow for live insertion of boards.
The
CY74FCT16245T
is
high-capacitance loads and low-impedance backplanes.
The CY74FCT162245T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for mini-
mal
undershoot
and
reduced
CY74FCT162245T is ideal for driving transmission lines.
The CY74FCT162H245T 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.
