Functional Description
These 16-bit, high-speed, low-power, registered transceivers
that are organized as two independent 8-bit bus transceivers
with three-state D-type registers and control circuitry arranged
for multiplexed transmission of data directly from the input bus
orfromtheinternalstorageregisters.OEABandOEBAcontrol
pins are provided to control the transceiver functions. SAB and
SBA control pins are provided to select either real-time or
stored data transfer.
Data on the A or B data bus, or both, can be stored in the
internal D flip-flops by LOW-to-HIGH transitions at the
appropriate clock pins (CLKAB or CLKBA), regardless of the
select or enable control pins. When SAB and SBA are in the
real-time transfer mode, it is also possible to store data without
using the internal D-type flip-flops by simultaneously enabling
OEAB and OEBA. In this configuration, each output reinforces
its input. Thus, when all other data sources to the two sets of
bus lines are at high impedance, each set of bus lines will
remain at its last state. The output buffers are designed with a
power-off disable feature that allows live insertion of boards.
The
CY74FCT16652T
is
high-capacitance loads and low-impedance backplanes.
The CY74FCT162652T 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
CY74FCT162652T is ideal for driving transmission lines.
