IDT54/74FCT162500AT/CT/ET
bit registered transceivers are built using advanced dual metal
CMOS technology. These high-speed, low-power 18-bit reg-
istered bus transceivers combine D-type latches and D-type
flip-flops to allow data flow in transparent, latched and clocked
modes. Data flow in each direction is controlled by output-
enable (OEAB and
OEBA), latch enable (LEAB and LEBA)
and clock (
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 port to A port is similar but uses
OEBA,
LEBA and
CLKBA. Flow-through organization of signal pins
simplifies layout. All inputs are designed with hysteresis for
improved noise margin.
The FCT16500AT/CT/ET are ideally suited for driving
high-capacitance loads and low-impedance backplanes. The
output buffers are designed with power off disable capability
to allow "live insertion" of boards when used as backplane
drivers.
The FCT162500AT/CT/ET have balanced output drive
with current limiting resistors. This offers low ground bounce,
minimal undershoot, and controlled output fall times–reducing
the need for external series terminating resistors.
The
FCT162500AT/CT/ET are plug-in replacements for the
FCT16500AT/CT/ET and ABT16500 for on-board bus inter-
face applications.
