TRANSCEIVER
DESCRIPTION:
The FCT162500T 18-bit registered transceivers are built using advanced
dual metal CMOS technology. These high-speed, low-power 18-bit registered
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 FCT162500T 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
FCT162500T are plug-in replacements for the FCT16500T and ABT16500
for on-board bus interface applications.
